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.

In 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.

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).

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.

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.

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.

First 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.""
Modern 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.
Through 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.",https://events.umich.edu/event/125502,"East Hall",3866,"East Hall",,"Graduate Students

Neural-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.

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.

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.

Discovering 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.

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.

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.",https://events.umich.edu/event/125498,"East Hall",1360,"East Hall",,Mathematics,"Financial/Actuarial Mathematics Seminar - Department of Mathematics

Face 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.
In 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.

Dr. 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.",https://events.umich.edu/event/126573,"East Hall",4448,"East Hall",,"Artificial Intelligence

Miller, University of Michigan","Lecture / Discussion","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 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.
