SUMMARY:Workshop / Seminar:An equator theorem for the 2-sphere
DESCRIPTION:We will focus on the group of Hamiltonian diffeomorphisms (and/or area-preserving homeomorphisms) of the 2-sphere. A tremendous amount of progress has been made in the study of these groups in the last few years\, but many problems remain\, including the Equator Conjecture. An equator on the 2-sphere is a simple closed curve whose complementary components have equal area. The Equator Conjecture predicts that for any positive K\, there are pairs of equators such that any Hamiltonian diffeomorphism sending one equator to the other must have Hofer norm larger than K. We will prove an alternative conjecture\, where we replace “Hofer norm” with “quantitative fragmentation norm”. To prove this\, we construct new quasimorphisms defined on the group of area-preserving homeomorphisms of the 2-sphere\, coming from methods inspired from mapping class groups and geometric group theory. Joint work with Yongsheng Jia.

SUMMARY:Workshop / Seminar:Student CA Seminar - Reduction modulo p
DESCRIPTION:Given a function f in Z[x_1\, ...\, x_n]\, for each prime p\, we can consider the image f_p in F_p[x_1\, ...\, x_n]. This family of prime characteristic models of f give us data about the original function f: for example\, if any of the polynomials f_p are irreducible over F_p\, then f is irreducible over Q.\n\nIn this talk\, we'll explain how we can construct a family of prime characteristic models to any algebraic variety X over C. These models encode tremendous amounts of information about the original variety. For instance\, X is smooth if and only if (X mod p) is smooth for infinitely many primes p. We will discuss various applications of this perspective\, including the following theorem:\n\nLet S be a regular ring containing Q or F_p and R a subring which is also a direct summand of S. Then R is Cohen-Macaulay.

SUMMARY:Workshop / Seminar:Math & MCAIM Colloquium: Homogenization of kirigami and origami-based mechanical metamaterials
DESCRIPTION:Mechanical metamaterials are many-body elastic systems that deform in unusual ways\, due to the interactions of nearly rigid building blocks. Examples include origami patterns with many folds\, or kirigami patterns made by cutting material from an elastic sheet. In either case\, the local deformations of the pattern involve internal degrees of freedom which must be matched with the usual global Euclidean invariances — e.g.\, groups of origami panels move by coordinated rotations and translations\, but it is still possible to bend the whole pattern into a curved shape. This talk will introduce the homogenization problem for kirigami and origami metamaterials to a broad audience\, and describe our recent results. Our goal is to explain the link between the design of the individual cuts/folds and the bulk deformations they produce. This is joint work with Paul Plucinsky (U. Southern California\, Aerospace and Mechanical Engineering) and Paolo Celli (Stony Brook U.\, Civil Engineering).\n\nThis talk will be mathematically self-contained\, not assuming a background in elasticity.\n\nEvent will be in-person and on Zoom: https://umich.zoom.us/j/98734707290

SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Bogomolov-Gieseker inequality and Bridgeland stability conditions
DESCRIPTION:Bridgeland stability conditions are powerful tools to study the derived categories of algebraic varieties. On smooth projective surfaces\, the classical Bogomolov inequality gives a bound for the second Chern character of stable sheaves. This thus implies the existence of the Bridgeland stability conditions on surfaces by the tilting technique. However\, to construct a Bridgeland stability condition on higher dimensional varieties\, a Bogomolov-Gieseker type bound for higher Chern characters is expected\, whose proof usually requires a stronger Bogomolov-Gieseker inequality. Besides Fano varieties and K3 surfaces\, it is difficult to prove a stronger Bogomolov-Gieseker inequality. In this talk\, I will start with definitions of Bridgeland stability conditions\, and then show how to use the Bogomolov inequality to construct the Bridgeland stability conditions on surfaces. Then I will show one way to prove a stronger Bogomolov-Gieseker inequality on some Calabi-Yau threefolds\, and as an application\, the existence of the Bridgeland stability conditions on such Calabi-Yau threefolds. If time permits\, I will mention another application of this stronger inequality by Feyzbakhsh-Thomas on enumerative invariants.

SUMMARY:Workshop / Seminar:Unified continuous-time q-learning for mean-field game and mean-field control problems
DESCRIPTION:We study the continuous-time q-learning in the mean-field jump-diﬀusion models from the representative agent’s perspective. We introduce the integrated q-function in decoupled form (decoupled Iq-function) and establish its martingale characterization together with the value function\, which provides a unified policy evaluation rule for both mean-field game (MFG) and mean-field control (MFC) problems. Moreover\, depending on the task to solve the MFG or MFC problem\, we can employ the decoupled Iq-function by diﬀerent means to learn the mean-field equilibrium policy or the mean-field optimal policy respectively. As a result\, we devise a unified q-learning algorithm for both MFG and MFC problems by utilizing all test policies stemming from the mean-field interactions. For several examples in the jump-diﬀusion setting\, within and beyond the LQ framework\, we can obtain the exact parameterization of the decoupled Iq-functions and the value functions\, and illustrate our algorithm from the representative agent’s perspective with satisfactory performance. Joint work with Xiang Yu and Xiaoli Wei.

SUMMARY:Workshop / Seminar:From circles and dots to separating curves in genus 2 (combinatorics seminar)
DESCRIPTION:Given 6 dots in the plane\, how many ways are there to separate them into two sets of 3 using a circle? Or using a Jordan curve? The first question can be answered by considering \"higher order Voronoi diagrams\"\; the latter can be answered by observing these diagrams have a \"plabic\" structure (in the sense of Postnikov). This gives a bijection between such Jordan curves and degree 1 cluster variables in the cluster algebra of type X7\, an exceptional cluster algebra about which little is known. This correspondence allows us to translate structure theorems about cluster algebras into remarkable results on the structure of Jordan curves with 3 dots on either side. As an application\, we translate these results into analogous results on \"separating curves in the closed surface of genus 2\"\; specifically\, we show that the g=2 separating curve complex is a strongly connected 6-dimensional pseudomanifold. On joint work with James Beyer and Jaewon Min.\n\nThis talk will take place in East Hall 4448.

SUMMARY:Workshop / Seminar:DE Seminar: Singularity Formation in Fluids
DESCRIPTION:Whether the 3D incompressible Euler equations can develop a finite-time singularity from smooth initial data is an outstanding open problem. In this talk\, I will discuss singularity formation in incompressible Euler equations with smooth data and boundary and present a framework for stable nearly self-similar blowup. In contrast to incompressible fluids\, singularity formation in compressible Euler equations has been established for a long time. However\, whether vorticity blows up in compressible fluids at the first singular time remains an open problem. We will generalize several methods and insights from incompressible fluids to establish vorticity blowup in compressible Euler equations with smooth and non-vacuous initial data.

SUMMARY:Lecture / Discussion:AIM Seminar: Physics and control of active matter
DESCRIPTION:Active matter\, i.e.\, internally driven matter fueled by a sustained dissipation of free energy\, is ubiquitous in the natural world. Examples range from bird flocks and human crowds to migrating cells and biopolymer gels\, including synthetic systems like phoretic colloids and robots. Such active materials exhibit emergent collective phenomena that break cherished conservation laws (of energy\, mass\, momentum\, etc.)\, and raise natural questions regarding how they can be controlled. I will discuss a few different vignettes on our recent efforts in this direction\, highlighting implications for the design of novel metamaterials and biomimetic constructs.\n\n\n\n\n\n\nContact: Silas Alben

SUMMARY:Workshop / Seminar:Student Algebraic Geometry Seminar: The Classification of Surfaces via Mori Theory
DESCRIPTION:The Enriques classification of algebraic surfaces was a milestone in the development of algebraic geometry and serves as inspiration for the birational classification of higher dimensional varieties pursued currently. I will discuss new phenomena that do not occur in the case of curves and introduce some crucial tools before presenting the classification according to the Kodaira dimension and birational invariants. I will present a proof using modern ideas from Mori’s minimal model program\, which extends to the dimension > 2 case.

SUMMARY:Lecture / Discussion:Student Logic and History of Math Seminar: The Axiom of Choice
DESCRIPTION:The Axiom of Choice\, now used throughout non-foundational mathematics with minimal hesitation\, has an extremely interesting history and many non-trivial consequences.\n\nFirst formulated explicitly by Ernst Zermelo to solve the so-called Well-Ordering Problem\, this axiom sparked debates throughout the mathematical community. David Hilbert\, arguably one of the greatest mathematicians of his time\, described Choice as the axiom \"most attacked up to the present in the mathematical literature\;\" and in Gregory Moore's words \"if the Axiom's most severe constructivist critics prevailed\, mathematics would be reduced to a collection of algorithms.\"\n\nModern mathematics\, however\, severely relies on the Axiom\, even if not in its full strength. Commonly used mathematical principles such as Zorn's Lemma\, the trichotomy of cardinals\, the right-invertibility of surjective functions\, and the existence of a basis for arbitrary vector spaces are all consequences of\, and\, in fact\, equivalent to\, the Axiom of Choice.\n\nThrough this inaugural talk of the Student Logic and History of Math Seminar\, we explore some of the history\, philosophy\, and mathematics surrounding the Axiom of Choice.

SUMMARY:Presentation:Dissertation Defense: Exploration of Quantum-Inspired Deep Learning Architectures for Fundamental Applications in Scientific Computing
DESCRIPTION:Abstract:\n\nNeural-network quantum states (NQS) is an exciting area of quantum-inspired machine learning\, wherein in a fully classical neural network is used to efficiently learn the optimal state vector for a quantum unsupervised learning problem\, bypassing the need to model the full exponentially large state space. In theory\, NQS architectures are broadly applicable\, and have been demonstrated successfully on several fundamental applications. We seek to further explore the practical utility of NQS as a black box solver for various applications in the scientific computing domain. We first present NQS as an explicit avenue for de-quantizing variational quantum eigensolvers\, demonstrating with the variational quantum linear solver (VQLS). We then explore the utility of VQLS and its de-quantization\, VNLS\, as black box solvers for a Newton-based linear complementarity solver\, used to model the time evolution of a rudimentary soil system. We introduce a new retentive network (RetNet) autoregressive NQS ansatz to solve electronic ground state calculations in computational quantum chemistry\, and we finish with a scaling law analysis of the RetNet architecture and its immediate autoregressive predecessors as applied to electronic structure calculations.\n\nHybrid Defense:\n5822 East Hall\nhttps://umich.zoom.us/j/92606555957

SUMMARY:Meeting:Student Combinatorics: Generalizing Polypositroids
DESCRIPTION:In their 2020 paper\, Thomas Lam and Alexander Postnikov define polypositroids\, the polytopal analog of positroids. However\, they also go one step further and observe that the definition of a polypositroid is secretly based on the type A root system. In this talk\, we’ll discuss how polypositroids can be extended to arbitrary finite root systems and examine how the parameterization of polypositroids can be generalized too.

SUMMARY:Workshop / Seminar:Ziwet Lecture I: Lorentzian Polynomials\, Matroids over Hyperfields\, and Related Topics
DESCRIPTION:Lorentzian polynomials serve as a bridge between continuous and discrete convex analysis\, with tropical geometry providing the critical link. The tropical connection is used to produce Lorentzian polynomials from discrete convex functions\, leading for example to a short proof of Mason's conjecture on the number of independent sets of a matroid. This lecture series will explore the intricate relationships among Grassmannians over hyperfields\, dequantization processes\, and the theory of Lorentzian polynomials. In ongoing collaborative work with Matt Baker\, Mario Kummer\, and Oliver Lorscheid\, we extend the connection between Lorentzian polynomials and discrete convex functions to matroids over triangular hyperfields\, as introduced by Viro. This extension deepens our understanding of the space of Lorentzian polynomials\, revealing a complex interplay among analysis\, combinatorics\, and geometry.\n\nThe three lectures in this series are designed to be accessible to a broad audience and appropriate for a Department Colloquium.\n\nAmong his many honors\, Prof. Huh is a recipient of the Fields Medal (2022)\, the MacArthur Fellowship (2022)\, and the New Horizons in Mathematics Prize (2019). He received his PhD in Mathematics from U-M in 2014.

SUMMARY:Workshop / Seminar:Learning Seminar in Algebraic Combinatorics: Hyperplane arrangements
DESCRIPTION:As David Speyer discussed last week\, hyperplane arrangements were a major motivation for the study of matroids. In this talk\, we’ll take a more in-depth look at hyperplane arrangements with a focus on their characteristic polynomials. While initially defined in terms the point count over F_q\, the characteristic polynomial can be computed entirely combinatorially from the intersection poset. Moreover\, in certain situations\, the characteristic polynomial has a physical interpretation\; over R\, it gives the number of connected components and\, over C\, it gives the Betti numbers. This talk will highlight these results and some of the techniques used to prove them.

SUMMARY:Workshop / Seminar:Rep Stability/Comm Alg Seminar: Stability in resolutions using local cohomology
DESCRIPTION:Murai observed an interesting stability pattern in the resolutions of symmetric monomial ideals. I will explain my preliminary attempt at providing a structural explanation to Murai's results by proving finiteness theorems for their local cohomology modules. Along the way\, I will also prove the Le--Nagel--Nguyen--Römer conjectures for sequences of GL_n-equivariant k[x_1\, x_2\, ...\, x_n]-modules when k is an infinite field of characteristic p > 0.

SUMMARY:Workshop / Seminar:Student Number Theory:The Ring of Periods
DESCRIPTION:We introduce and define the ring of periods\, a subring of the complex numbers defined by Kontsevich and Zagier consisting of \"numbers of arithmetic origin.\" This ring includes all algebraic numbers\, but also some transcendental numbers\, such as pi. We give examples of periods and state some of the major conjectures involving this ring\, including deep connections with arithmetic geometry and PDE's.

SUMMARY:Workshop / Seminar:Football vs. table tennis: which is the better sport?
DESCRIPTION:To answer the question posed in the title\, we first need to define what we mean by \"better.\" In this talk\, we will look at the tournament designs of football and table tennis from an optimal stopping perspective. In particular\, we consider the problem of finding the optimal scheme for a knock-out tournament with 2^n players\, aiming at determining the top player. In each game in the tournament\, we observe a real-time score\, modeled by a Brownian motion with drift where the drift reflects the players' relative abilities. We can stop observing the game when the outcome seems clear and decide who advances. However\, the longer a match is played\, the more cost one needs to pay. We formulate and solve a stopping problem to minimise the probability of eliminating the best player while keeping the cost of observation low. The result will tell us how to smartly distribute the time cost across tournament games\, and thus\, reveals which sport has a superior design. Additionally\, we discuss a few variants of the problem and some possible generalisations.

SUMMARY:Workshop / Seminar:Ziwet Lecture II: Lorentzian Polynomials\, Matroids over Hyperfields\, and Related Topics
DESCRIPTION:Lorentzian polynomials serve as a bridge between continuous and discrete convex analysis\, with tropical geometry providing the critical link. The tropical connection is used to produce Lorentzian polynomials from discrete convex functions\, leading for example to a short proof of Mason's conjecture on the number of independent sets of a matroid. This lecture series will explore the intricate relationships among Grassmannians over hyperfields\, dequantization processes\, and the theory of Lorentzian polynomials. In ongoing collaborative work with Matt Baker\, Mario Kummer\, and Oliver Lorscheid\, we extend the connection between Lorentzian polynomials and discrete convex functions to matroids over triangular hyperfields\, as introduced by Viro. This extension deepens our understanding of the space of Lorentzian polynomials\, revealing a complex interplay among analysis\, combinatorics\, and geometry.\n\nThe three lectures in this series are designed to be accessible to a broad audience and appropriate for a Department Colloquium.\n\nAmong his many honors\, Prof. Huh is a recipient of the Fields Medal (2022)\, the MacArthur Fellowship (2022)\, and the New Horizons in Mathematics Prize (2019).

DESCRIPTION:Draisma recently proved that finite length polynomial representations of the infinite general linear group GL are topologically GL-noetherian\, i.e.\, the descending chain condition holds for GL-stable closed subsets. The scheme-theoretic variant of this theorem is a major open problem in the area. I will briefly outline the rich history of this problem and provide a negative answer in characteristic two.

SUMMARY:Workshop / Seminar:Student Algebraic Geometry: Complete Intersections of Two Quadrics in Projective Space
DESCRIPTION:Complete intersections in projective space are\, behind hypersurfaces\, perhaps the easiest varieties to study\, but even in simple cases can have interesting geometry. In the simplest non-trivial case of a complete intersection we can intersect two smooth quadric hypersurfaces\, and even in this case the resulting variety X turns out to be worthy of study. I will discuss some of the interesting aspects\, including the rationality of X and how one can associate to X a hyperelliptic curve (under a condition on the parity of dim X).

SUMMARY:Lecture / Discussion:Student Logic and History of Math Seminar: An Introduction to Modal Logic
DESCRIPTION:Through the early and mid-20th century\, modal logics were developed as a syntactic extension of propositional logic to more faithfully capture aspects of natural language. We will describe a modal extension of propositional logic called S4 and its Kripke semantics\, introducing propositional logic along the way. We'll then revisit some of the original issues motivated by natural language and possibly some mathematical applications.

SUMMARY:Workshop / Seminar:GLNT: Categorical equivalences in Local Geometric Langlands
DESCRIPTION:Abstract: Let F be an equal characteristic local field and G a reductive group. It is known that by type theory that representations of G(F) can be understood as modules over various associative algebras\, called Hecke algebras. In particular tamely ramified principle series are modules of the affine Hecke algebra. Based on this interpretation and a realization of the affine Hecke algebra using equivariant K-theory\, Kazhdan and Lusztig proved the Deligne-Langlands correspondence. A geometrization of such correspondence was studied by Roman Bezrukavnikov\, by proving a coherent realization of the affine Hecke category. In this talk\, I will give an equivalence between certain deeper level Hecke categories with affine Hecke categories of a smaller group H (usually a twisted Levi of loop group LG)\, therefore relating wildly ramified representations with tamely ramified ones of H.

SUMMARY:Workshop / Seminar:Student CA Seminar - Castelnuovo-Mumford regularity
DESCRIPTION:Abstract: The Cartan-Serre-Grothendieck theorem implies that all the cohomological subtleties associated to a coherent sheaf on a projective space disappear after twisting by a sufficiently high multiple of the hyperplane line bundle. Castelnuovo-Mumford regularity gives a quantitative measure of how much one has to twist in order that these properties take effect. It then governs the algebraic complexity of a coherent sheaf. In this talk\, we give the definition and basic properties of Castelnuovo-Mumford regularity\, and introduce some applications.

DESCRIPTION:In this talk\, we will discuss the definition of matroids and their properties. As alluded to in previous talks\, matroids generalize the notion of linear independence of subsets of some ambient set. We will discuss some examples of matroids and recipes to get them from more concrete objects. Furthermore\, we will define terms such as basis\, spanning sets\, rank\, and flats\, as well as the associated lattice of flats of a matroid\, generalizing ideas like the intersection poset from the theory of hyperplane arrangements.

SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Stability conditions on surface root stacks
DESCRIPTION:Compared to varieties\, vector bundles and derived categories on stacks are less understood. (Bridgeland) stability conditions are effective to study these objects\, however in general they are difficult to construct. In this talk we construct tilt stability conditions on root stacks over smooth surfaces\, and show their deformation dimension is at least as the even rational Chen-Ruan cohomology. I will recall the structure of derived categories of root stacks and the notion of Chen-Ruan cohomology. Then I will show the ideas of proof via 2 key examples. We will also discuss some potential further questions and applications.

SUMMARY:Workshop / Seminar:RTG Seminar Geometry\, Dynamics\, Topology: Proper affine deformations of positive representations
DESCRIPTION:We show that every positive representation of a free group into SO(2n\,2n-1) admits R^{4n-1}-valued cocycles giving rise to proper affine actions on affine (4n-1)-space. We can explicitly find such deformations using generalized infinitesimal strip deformations inspired by the work of Danciger-Gueritaud-Kassel. We also exhibit a fundamental domain for such a proper action bounded by crooked hyperplanes. This is joint work with Jean-Philippe Burelle.

SUMMARY:Lecture / Discussion:AIM Seminar: Harnessing Structural Periodicity for Wave Control Toward Sensing\, Harvesting\, and Space Applications
DESCRIPTION:The study of structural periodicity in engineered materials\, such as metamaterials\, phononic crystals\, and metasurfaces\, has opened new frontiers in wave control. Our research group explores the fundamental principles and advanced techniques for harnessing structural periodicity to manipulate wave propagation for diverse applications in sensing\, energy harvesting\, and space technology. By leveraging the unique properties of these periodic structures\, we demonstrate how they can be used to enhance ultrasonic sensing and nondestructive testing\, improve the efficiency of energy harvesters\, and develop innovative solutions for space applications. The first part of my talk will focus on gradient index phononic crystal (GRIN-PC) lenses conforming pipe-like structures. Conformal GRIN-PC lenses are designed by tailoring unit cell geometry according to a specific refractive index profile. We explore the focusing of multi-mode guided waves at the desired locations (i.e. sensor nodes) along the pipe structure to address the attenuation problem in long-range pipelines. Then\, I will explain how we exploit the negative refraction property of phononic crystals for designing a super lens. Unlike GRIN-PC lenses\, which have at least minimum wavelength resolution as their natural limit\, negative refraction-based PC lenses can potentially overcome the diffraction limit\, which is highly favorable in medical imaging or other applications requiring localized wave intensity in areas smaller than a square wavelength. The second part of my talk will deal with reconfigurable metasurfaces for full wavefront control with an emphasis on energy harvesting of low frequency elastic waves. We fully analyze and design the elastic metasurfaces by tailoring the phase gradient of individual unit structures for different wave functions and present theoretical findings along with experimental validation. The last part of my talk will highlight the potential of metamaterials in space applications\, such as novel in-space manufacturable extended solar arrays and antennas with high precision and mass efficiency.\n\nContact: Silas Alben

SUMMARY:Workshop / Seminar:Forks and their uses (combinatorics seminar)
DESCRIPTION:Mutation-finite quivers --- those mutation-equivalent to only a finite number of quivers --- are relatively well-understood objects. However\, their counterpart\, mutation-infinite quivers\, are not. Using a special type of quiver called a fork\, we give two results related to mutation-infinite quivers. First\, we prove that a quiver being mutation-equivalent to a finite number of non-forks is a hereditary property\, i.e.\, one preserved by restriction to any full subquiver. Second\, using only forks and elementary methods\, we show that 3-vertex quivers that are not mutation-equivalent to an acyclic quiver have sign-coherent c-vectors.

SUMMARY:Presentation:Developmental Psychology Visiting Scholar Talk: Early Life Stress and Children’s Learning: What Matters Most Might Not Be Obvious
DESCRIPTION:Hosted by the Lorraine Nadelman Visiting Scholar Fund\n\nDiscovering the processes through which early life experiences affect children’s development is critically important for developing prevention and interventions for youth exposed to adversity\, and also for understanding the basic science of human development and learning. Nearly all research on early experience\, socio-emotional development\, and neurobiology has been anchored on documenting specific (presumably stressful) events that have occurred in a child’s life. Yet\, there is increasing evidence that children’s perceptions of their own experiences and the meaning they construe from what has happened to them might be critical for understanding behavioral\, biological\, and learning outcomes. How can we better embrace this real- albeit messy- complexity of human development? This presentation aims to serve as a catalyst for thinking about these kinds of new future research directions.

SUMMARY:Workshop / Seminar:GLNT: Zero cycles on a product of elliptic curves
DESCRIPTION:Abstract: I will discuss some numerical evidence for part of the Bloch-Beilinson conjecture for zero cycles on a product of elliptic curves over a number field\, namely the injectivity of the Abel-Jacobi map modulo torsion. These examples were computed around ten years ago (in joint work with V. Srinivas) but never published. To a large extent\, this work has been superseded by recent work of Valia Gazaki and Jonathan Love\, nevertheless the original examples and methods (which are somewhat different) may be of some interest.

SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Generalized Beauville decomposition for degenerate abelian fibrations
DESCRIPTION:For a family of abelian varieties\, the rational cohomology/relative Chow motive has a canonical decomposition into pure weight spaces by Beauville and Deninger-Murre. A degenerate abelian fibration is a fibration which is an abelian fibration generically but admits singular fibers on the boundary. It is a natural question to ask whether some of the structure remains to hold for degenerate abelian fibrations. In this talk\, we consider perverse filtration on the rational cohomology of the relative compactified Jacobian and ask when the filtration has Fourier-stable multiplicative splitting. I will explain that if the relative compactified Jacobian arises from the Beauville-Mukai system\, we get such multiplicative splitting. On the other hand\, for the general family of integral curves\, even for the family of nodal curves\, we show that such multiplicative splitting cannot exist. This is a joint work with D. Maulik\, J. Shen and Q. Yin.

SUMMARY:Workshop / Seminar:Long-time behaviors of stochastic linear-quadratic optimal control problems.
DESCRIPTION:This paper investigates the asymptotic behavior of the linear-quadratic stochastic optimal control problems. By establishing a connection between the ergodic cost problem and the so-called cell problem in the homogenization of Hamilton-Jacobi equations\, we reveal the turnpike properties of the linear-quadratic stochastic optimal control problems from various perspectives.

SUMMARY:Workshop / Seminar:RTG Seminar Geometry\, Dynamics and Topology: Big Mapping Class Groups in Dimensions 0\, 1\, and 2
DESCRIPTION:We will give a gentle introduction to the world of big mapping class groups. These arise as groups of topological symmetries of: Infinite-type surfaces (dimension 2)\, locally finite\, infinite graphs (dimension 1)\, and closed subsets of Cantor sets\, i.e. second countable Stone spaces (dimension 0). These groups are all uncountable and come equipped with a topology that makes them into non-locally compact (aka \"huge\") Polish groups. We will survey some of the rich and interesting interplay between the topological\, geometric\, and algebraic aspects of these groups. Our main motivation will be to propose these groups as a fertile testing ground for extending the tools of geometric group theory beyond finitely (or compactly) generated groups to general \"huge\" groups\; however\, we will also mention potential connections to other fields of geometry\, topology\, and dynamics.

SUMMARY:Workshop / Seminar:Operahedron Lattices (Combinatorics Seminar)
DESCRIPTION:Two classical lattices are the Tamari lattice on bracketings of a word and the weak order on permutations. The Hasse diagram of each of these lattices is the oriented 1-skeleton of a polytope\, the associahedron and the permutohedron respectively.\n\nWe examine a poset on bracketings of rooted trees whose Hasse diagram is the oriented 1-skeleton of a polytope called the operahedron. We show this poset is a lattice which answers a question of Laplante-Anfossi. These lattices provide an extremely natural generalization of both the Tamari lattice and the weak order.\n\nNo knowledge of lattices or polyhedral combinatorics is assumed.

SUMMARY:Workshop / Seminar:Colloquium Seminar: On the effective dynamics of Bose-Fermi mixtures
DESCRIPTION:Investigating degenerate mixtures of bosons and fermions is an extremely active area of research in experimental physics for constructing and understanding novel quantum bound states such as those in superconductors\, superfluids\, and supersolids. These ultra-cold Bose-Fermi mixtures are fundamentally different from degenerate gases with only bosons or fermions. They not only show an enriched phase diagram\, but also a fundamental instability due to energetic considerations coming from the Pauli exclusion principle. Inspired by this activity in the physics community\, recently we started exploring the mathematical theory of Bose-Fermi mixtures. One of the main challenges is understanding the physical scales of the system that allow for suitable analysis. We will describe how we overcame this challenge by identifying a novel scaling regime in which the fermion distribution behaves semi-clasically\, but the boson field remains quantum-mechanical. In this regime\, the bosons are much lighter and more numerous than the fermions. The talk is based on joint work with Esteban Cardenas and Joseph Miller.

SUMMARY:Workshop / Seminar:Existence of Optimal Stationary Singular Controls and MFG Equilibria
DESCRIPTION:We examine the stationary relaxed singular control problem within a multi-dimensional framework for a single agent\, as well as its Mean Field Game (MFG) equivalent. We demonstrate that optimal relaxed controls exist for both maximization and minimization cases. These relaxed controls are defined by random measures across the state and control spaces\, with the state process described as a solution to the associated martingale problem. By leveraging findings from \cite{kur-sto}\, we establish the equivalence between the martingale problem and the stationary forward equation. This allows us to reformulate the relaxed control problem into a linear programming problem within the measure space. We prove the sequential compactness of these measures\, thereby confirming the feasibility of achieving an optimal solution. Subsequently\, our focus shifts to Mean Field Games. Drawing on insights from the single-agent problem and employing Kakutani--Glicksberg--Fan fixed point theorem\, we derive the existence of a mean field game equilibria.

SUMMARY:Workshop / Seminar:Cyclically ordered quivers (Combinatorics Seminar)
DESCRIPTION:Quivers and their mutations play a fundamental role in the theory of cluster algebras. We focus on the problem of deciding whether two given quivers are mutation equivalent to each other. Our approach is based on introducing an additional structure of a cyclic ordering on the set of vertices of a quiver. This leads to new powerful invariants of quiver mutation. These invariants can be used to show that various quivers are not mutation acyclic\, i.e.\, they are not mutation equivalent to an acyclic quiver. This talk is partially based on joint work with Sergey Fomin [arXiv:2406.03604].

SUMMARY:Lecture / Discussion:Foundations and Frontiers Speaker Series
DESCRIPTION:Presentation Abstract\nFace processing plays a central role in everyday human life. We investigate the nature of face representation and processing in the brain\, by adapting and developing appropriate machine learning and computer vision methods. In the Foundations portion of the lecture\, I will be giving a review of the technical methods utilised in our modeling work to model the psychological face space\, including the relevant computer vision and deep neural network models\, as well as more classical methods such as multi-dimensional scaling. I will also introduce a novel way of doing regression developed in our lab\, and describe its theoretical guarantees and implications for scientific data analysis and interpretation.\n\nIn the Frontiers portion of the lecture\, I will describe our work using the Active Appearance Model\, which has recently been shown to have latent features encoded by face processing neurons in the primate brain\, to show that human social trait perception has both a linear component and a quadratic component\, with the latter specifically related to the statistical typicality of a face defined as log likelihood of the face under the population face distribution. I will relate this typicality element to the coding cost of maximally efficient neural representation\, and describe its implications for learning and exploration. In the cognitive domain\, we examine how attentional modulation affects face representation and perception. In the social domain\, we examine how facial processing affects social perception and judgment\, with implications for gender and racial biases. In the psychiatric domain\, we examine how depression and anxiety in an individual interact with face perception and face-based decision making. \n------\nSchedule\n2:00-2:30 pm Foundations Presentation\n2:30-2:40 pm Q & A\n—10 minute break—\n5:50-3:20 pm Frontiers Presentation\n3:20-3:30 pm Q & A\n-----\nDr. Yu conducts research at the intersection of natural and artificial intelligence. Her group uses mathematically rigorous and algorithmically diverse tools to understand the nature of representation and computations that give rise to intelligent behavior\, with particular regard to the challenges posed by inferential uncertainty and the opportunities afforded by volitional control. Using diverse machine learning and statistical tools\, e.g. Bayesian statistical modeling\, control theory\, reinforcement learning\, and information theory\, theoretical frameworks and mathematical models are developed to explain disparate aspects of cognition importation for intelligence: perception\, attention\, decision-making\, learning\, cognitive control\, active sensing\, economic behavior\, and social interactions. After completing her bachelor’s at MIT\, PhD at UCL Gatsby Computational Neuroscience Unit\, and postdoc training at Princeton University\, Dr. Yu was faculty at UCSD Cognitive Science for 14 years before joining TU Darmstadt in Germany as an Alexander von Humboldt AI Professor in late 2022. With her interdisciplinary expertise and interest\, Dr. Yu’s arrival strengthens and complements research at the Centre for Cognitive Science at TU Darmstadt and at hessian.AI\, the Centre for Artificial Intelligence of Hesse based in Darmstadt. Her new group currently has positions open for postdocs\, PhD students\, master’s students\, research interns\, and visiting scholars.

SUMMARY:Workshop / Seminar:Sequential optimal contracting in continuous time
DESCRIPTION:In this talk I will present a principal-agent problem in continuous time with multiple lump-sum payments (contracts) paid at different deterministic times. Based on the approach introduced in Cvitanić-Possamai-Touzi\, we reduce the non-zero sum Stackelberg game between the principal and agent to a standard stochastic optimal control problem. We apply our result to a benchmark model for which we investigate how different inputs (payment frequencies\, payment distribution\, discount factors\, agent's reservation utility\, renegotiation) affect the principal's value. This is a joint work with Erhan Bayraktar\, Ibrahim Ekren\, and Liwei Huang.

SUMMARY:Lecture / Discussion:AIM Seminar: Extreme Superposition: Models for Large-Amplitude Rogue Waves
DESCRIPTION:Rogue waves or freak waves are spatially-localized disturbances of a background field that are also temporally localized. In the setting of the focusing nonlinear Schrödinger equation\, which is a universal model for the complex amplitude of a wave packet in a general one-dimensional weakly nonlinear and strongly dispersive setting that includes water waves and nonlinear optics as special cases\, a special exact solution exhibiting rogue-wave character was found by D. H. Peregrine in 1983. Since then\, with the help of complete integrability\, Peregrine’s solution has been generalized to a family of solutions of arbitrary “order” where more parameters appear in the solution as the order increases. These parameters can be adjusted to maximize the amplitude of the rogue wave for a given order. This talk will describe several recent results concerning such maximal-amplitude rogue wave solutions in the limit that the order increases without bound. For instance\, it turns out that there is a limiting structure in a suitable near-field scaling of the peak of the rogue wave\; this structure is a novel exact solution of the focusing nonlinear Schrödinger equation — the “rogue wave of infinite order” — that is also connected with the hierarchy of the third Painlevé equation. This is joint work with Deniz Bilman and Liming Ling.

SUMMARY:Lecture / Discussion:AIM Seminar: Ideology-ology: Diagnostic Perspectives and Reality-Seeking Dynamical Modeling of the US Political Ecosystem
DESCRIPTION:The US political arena is generally a bleak mix of distressing and aggravating\, particularly in the current highly polarized climate\, but that distress only increases the need to honestly and scientifically understand the forces at play in ideological space\, and the polarization offers emergent simplicity and thus a unique opportunity for mathematical modeling. This talk will share some recent and ongoing attempts to visualize and understand the current political landscape\, as well as some quantitative patterns in political psychology and the modern information ecosystem. These recently-gathered data inform a mechanistic dynamical model of ideological drift\, allowing theory to extrapolate the complex implications of micro-scale data to macro-scale outcomes---while iteratively improving and suggesting further data-gathering efforts to corner remaining uncertainty. The first waves of results from this perspective provide some remarkable insights\, providing some hope of understanding and productively informing political messaging and algorithmic design for a more reasonable political future.
