SUMMARY:Workshop / Seminar:Math Grad Show and Tell Seminar: The surprising asymptotics of bingo
DESCRIPTION:Inspired by Okta Verify Bingo in the graduate lounge\, consider an N by N square of cells. Every second\, a uniformly random cell is chosen (with replacement) and filled in. What is the expected amount of time until a bingo\, i.e. a fully filled in row\, column\, or diagonal? How does this grow asymptotically as N increases? The answer involves some interesting mathematics and may surprise you.

SUMMARY:Lecture / Discussion:Dynamics seminar: Dynamics of the Secant Method and Other Monomial-Type Maps
DESCRIPTION:We discuss the secant method\, a root-finding algorithm alternative to Newton’s method. Given a rational map f : P^1 -> P^1\, the secant method yields a dynamical system Sf on P^1 x P^1 (minus a finite indeterminacy locus). If r in C is a simple root of f\, then the point (r\, r) is an attracting fixed point of Sf.\n\nAdditionally\, when 0 is a simple root of f with f’’(0) nonzero\, we have that Sf is an instance of the broader class of “monomial-type maps.” A “monomial map” is simply a function whose output coordinates are all monomials in the input coordinates. A “monomial-type map” is then a coordinate-by-coordinate scaling of a monomial map by some holomorphic scalar functions. In the aforementioned case for 0 and Sf\, we find that Sf(x\, y) = (a(x\, y) * xy\, x). \n\nBy extending the 1-dimensional constructions of Böttcher coordinates and Green’s functions to these higher-dimensional monomial-type maps\, we can show that (1) Sf has well-defined dynamical potential\, (2) it takes the vequipotential to the v^φ equipotential (where φ is the golden ratio)\, and (3) Sf is locally modeled by the Fibonacci monomial map (x\, y) |-> (xy\, x)\, whose dynamics are well-understood.

SUMMARY:Workshop / Seminar:Permutation & Braid Actions on Decorated Flags
DESCRIPTION:A decorated flag is a nested sequence of linear subspaces\, each equipped with a nonzero volume element. In this talk\, we will introduce a permutation action on decorated flags compatible with certain linear operators. We will explore this action through explicit calculations in the three-dimensional case\, and explain how it relates to a permutation action constructed by Goncharov and Shen in 2016. Finally\, we will briefly introduce a family of braid actions and explore when they recover the permutation actions.

SUMMARY:Workshop / Seminar:Math for AI Safety: Toy Models of Superposition
DESCRIPTION:This semester\, our reading group will focus on Interpretability Theory. \n\nFor this week\, we are reading Toy Models of Superposition\, Sections 1\, 2\, 3(optional)\, 4\, and 8. \nhttps://transformer-circuits.pub/2022/toy_model/index.html\nThe paper studies how neural networks can represent more features than they have dimensions by storing multiple features in overlapping directions — a phenomenon called superposition. This has a number of implications. In particular\, there is a trade off between the benefit of representing more concepts and interference between features. This seminar will start with a 10 minute summary lecture followed by group discussions.

SUMMARY:Workshop / Seminar:Student Commutative Algebra: Valuation rings in characteristic p and Abhyankar valuations
DESCRIPTION:This is basically an exposition of the paper \"Frobenius and Valuation Rings\" by Rankeya Datta and Karen Smith. We shall look at the interaction of non-Noetherian valuation rings (i.e.\, non-DVRs) in char p with the Frobenius endomorphism and give an example of a non-excellent DVR arising as a valuation ring in a function field. We shall also look at a necessary and sufficient condition for a valuation to be Abhyankar.

SUMMARY:Workshop / Seminar:Student Number Theory: The Gross-Zagier formula
DESCRIPTION:The Gross-Zagier formula relates the Néron-Tate height of a Heegner point to the central derivative of a Rankin L-function. Combined with Kolyvagin's theory of Euler systems\, it establishes the weak Birch and Swinnerton-Dyer conjecture for elliptic curves over Q of analytic rank one.\n\nWe begin by outlining the ideas behind Gross and Zagier's earlier factorization formula for differences of singular moduli\, which can be viewed as the local height computation in the special case N=1. For general N\, Gross's algebraic approach computes non-archimedean local height pairings\, while Zagier's analytic approach computes archimedean local height pairings. On the L-function side\, Rankin's method expresses the central derivative as the Petersson inner product with an explicit cusp form. The Gross-Zagier formula then follows by comparing this cusp form with the generating series of height pairings\, up to an oldform.\n\nWe conclude with a brief overview of recent developments in the field.

SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Valuatively independent bases for Calabi-Yau varieties
DESCRIPTION:From the perspective of the Gross-Siebert program\, the mirror symmetry of Calabi-Yau varieties is governed by certain canonical bases for the sections of the powers of an ample line bundle on a degeneration. It is expected that the pairing between these basis elements and valuations in the essential skeleton satisfies an independence condition\, similar to the pairing between monomials and monomial valuations on a toric variety. In this talk\, I will explain how tools from birational geometry and K-stability can be used to construct bases that fulfill this condition. This is joint work with Yuchen Liu.

SUMMARY:Workshop / Seminar:RTG SEMINAR GeometryTopologyDynamics:  TWO INVARIANTS OF TYPE-PRESERVING REPRESENTATIONS AND APPLICATIONS
DESCRIPTION:Abstract:  We investigate the representations of surface groups into PSL(2\, R). For a closed surface\, by the classical result of Goldman\, the Euler class provides a complete classification of the connected components of the character variety. However\, describing these components becomes more subtle when considering the type-preserving representations for punctured surfaces. In this talk\, I will introduce two invariants of type-preserving representations that characterize the connected components. As an application\, I will show the existence of totally hyperbolic representations\, giving a negative answer to a question of Bowditch. I will also discuss the relation between the existence of such representations and the mapping class group action on the relative character variety.

SUMMARY:Workshop / Seminar:Student AIM Seminar: The State of Local LLMs
DESCRIPTION:In the last few months\, there has been rapid development in the world of local LLMs\, which can run in PCs and laptops with enough RAM and a GPU. Though still far behind from frontier models\, local LLMs can still write code\, transcribe handwritten notes to LaTeX\, and perform other agentic tasks without sending any data to a third party. In this talk we will explore the wide range of local LLMs that exist\, what sets them apart from each other and areas where they are still lacking. We will also learn how to run these models\, set up your own workflows and evaluate their outputs.

SUMMARY:Workshop / Seminar:DE Seminar: Wave Turbulence for Oscillator Chains
DESCRIPTION:In this talk\, we discuss the wave turbulence properties of the Fermi-Pasta-Ulam-Tsingou (FPUT) system for coupled harmonic oscillators. While it was initially predicted that the system should exhibit thermalization\, numerical experiments showed quasi-periodic behavior\, giving rise to the so-called ``FPUT paradox\". Here\, we demonstrate thermalization in a weakly nonlinear regime for the $\beta$-FPUT by deriving the kinetic equation. Some notable aspects of the derivation are the time constraints imposed by the 1D nature of the system\, the impact of non-resonant terms in the nonlinearity\, and the need for a time-dependent phase renormalization in the system to remove divergent interactions.

SUMMARY:Lecture / Discussion:AIM Seminar: Geometry for Physics Simulation
DESCRIPTION:Abstract: Advances in simulation and scientific machine learning have made computation an engine of discovery. For increasingly complex physical systems\, however\, computational scale and model expressiveness alone may not suffice for faithful simulation\, exploration\, and inverse design. General-purpose representations often describe a space much larger than the set of physically admissible states. Computing in this larger space can require substantial effort to ensure that solutions respect the underlying geometry\, topology\, and conservation laws. A complementary path is to make this structure explicit. Through examples ranging from bending rods and slithering snakes to fluid flows and magnetic fields in plasmas\, this talk shows how geometric insight can make difficult problems computationally tractable\, how the resulting structure can be preserved and encoded in algorithms\, and how the exchange among theory\, discretization\, and application yields new mathematics alongside more effective computational tools.\n\n\nContact: Ian Tobasco

SUMMARY:Workshop / Seminar:On the Algebra of Moving Window Calculations
DESCRIPTION:Moving window calculations arise throughout applied mathematics\, computer science\, and engineering. Familiar examples include moving sums\, maxima\, and filters\, but the same basic problem also appears in more general windowed recurrences. In this talk\, we show that a large class of such calculations admits a common algebraic formulation. In the associative setting\, moving window calculations can be recast as exponentiation in a semidirect product\, bringing efficient powering algorithms to bear. In more general settings\, semi-associativity provides the right framework for representing compositions of updates and understanding when efficient computation is still possible. This point of view not only unifies a broad family of examples\, but also leads naturally to compact vectorized implementations\, making the methods well suited to modern GPU architectures. This is joint work with David Maslen.

SUMMARY:Workshop / Seminar:Student Algebraic Geometry: Compactifications of Siegel Modular Varieties
DESCRIPTION:The Siegel upper half-space H_g serves as a natural generalization of the upper half-plane. Indeed\, just as M_{1\,1} = A_1 is the quotient H/SL_2(Z)\, one can show that A_g\, the space of principally polarized abelian varieties of dimension g\, is isomorphic to H_g/Sp_{2g}(Z). More generally\, one can consider spaces H_g/Gamma for any arithmetic subgroup Gamma in Sp_{2g}(Q). Unlike M_g\, which admits the canonical Deligne-Mumford compactification\, these spaces admit many natural compactifications with different geometric properties. In this talk\, we introduce H_g/Gamma\, the Siegel modular varieties\, and discuss various compactifications such as the Baily–Borel compactification and toroidal compactifications. We then focus on the specific case of g = 2 to showcase the beautiful arithmetic that occurs even in this small case.

SUMMARY:Workshop / Seminar:GLNT: Arithmetic intersections on non-split Cartan modular curves
DESCRIPTION:Abstract: Take two CM elliptic curves over a number field\, each equipped with a level structure preserved by all endomorphisms. At which primes $p$ does there exist an isomorphism between the elliptic curves mod $p$ that preserves the level structures? This question was answered for $\Gamma_0(N)$ level structure by Gross\, Kohnen\, and Zagier in 1987. A key step in their proof is showing that an isomorphism mod $p$ determines embeddings of the (quadratic) CM orders into a common (quaternion) Eichler order. In this talk\, we will discuss what changes in the argument when we replace $\Gamma_0(N)$ with the normalizer of a non-split Cartan subgroup. This is joint work with Elie Studnia and Jan Vonk.

SUMMARY:Livestream / Virtual:ISRMT Seminar:  Many Body Asymptotics for the Toda Lattice
DESCRIPTION:Abstract: The Toda lattice prescribes the evolution of many particles interacting under certain Hamiltonian dynamics\; it is an archetypal example of a completely integrable system. In this talk we describe several results providing the long-time asymptotics of this system\, under random\, dense initial data. The proofs proceed by finding a way to interpret the Toda lattice as a collection of \"quasi-particles\" that behave similarly to solitons\, and providing a framework to study how these quasi-particles asymptotically evolve in time. The arguments use ideas from random matrix theory\, particularly the analysis localization phenomena for eigenvectors of random tridiagonal matrices.\n\n*To request access to the Zoom room\, please contact Nathan Hayford at nhayford [ at ] umich.edu*

SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Stable map resolutions of Richardson varieties
DESCRIPTION:Given a circle action S on a projective variety X\, we introduce the \"stable map quotient\" using Kontsevich's space of stable maps of curves. In the case that X is a Richardson variety (the intersection of a Schubert with an opposite Schubert variety)\, generally very singular\, the quotient is nonetheless smooth! I'll use this to give a log resolution of Richardson varieties\, and describe the dual simplicial complex to the anticanonical sncd boundary.

SUMMARY:Workshop / Seminar:A New Approach for the Continuous Time Kyle-Back Strategic Insider Equilibrium Problem
DESCRIPTION:In this talk\, we consider a continuous-time Kyle-Back model which is a game between an insider and a market maker. The existing literature typically focuses on constructing equilibria with a PDE approach\, which requires certain Markovian structures. We characterize all equilibria through a coupled system of forward-backward SDEs. In particular\, when the time duration is small\, we show that the FBSDE is well-posed\, and therefore the game has a unique equilibrium. Moreover\, this unique equilibrium may be non-Markovian and thus not attainable via the PDE approach. We next study the set value of the game\, which roughly speaking is the set of insider's values over all equilibria and thus is by nature unique. Finally\, we characterize the set value through a level set of a certain standard HJB equation.\nIn the second part of the talk\, we apply the new approach to the Kyle-Back model with dynamic legal risk and large numbers of noise traders. In this setting\, the insider chooses a strategy that conceals his identity within a large volume of surrounding trades and concentrates on medium-sized trades.  We establish an intensity-based mathematical framework for explaining the interconnections between insider trading and stealth trading. When the number of noise traders becomes large\, the price impact of the insider asymptotically vanishes\, and consequently the stochastic game becomes deterministic optimizations\, which also carry implications for regulatory investigations and sanctions.\n\nThe results above include the joint work with Weixuan Xia and with Jianfeng Zhang.

SUMMARY:Workshop / Seminar:Recovering Geometry from Random Graphs
DESCRIPTION:How much geometry can be recovered from a random graph? Consider points sampled from an unknown space\, with edges drawn independently according to a function of the distance between their endpoints. I will discuss a sequence of results on efficient reconstruction when the underlying space is a manifold\, including results for sparse graphs and for unknown connection functions.  I will also explain what makes manifold geometry special and illustrate the information-theoretic obstructions that arise in more general metric spaces.\nBased on joint work with Pakawut Jiradilok and Elchanan Mossel.

SUMMARY:Lecture / Discussion:Dynamics seminar: Arithmetic polyhedra
DESCRIPTION:The Koebe-Andreev-Thurston construction associated to every combinatorial 3d polyhedron is a canonical 3d hyperbolic polyhedron\, which happens to be right-angled and ideal.  In particular\, it is the fundamental domain for the Coxeter group generated by the reflections across its facets.  We answer the question: when is this group arithmetic?

SUMMARY:Workshop / Seminar:Inverse problems over probability measure space
DESCRIPTION:Inverse problems are ubiquitous. Traditionally\, the goal is to infer an unknown vector or function. But what if the unknown is a probability measure? Seeking a measure that generates data consistent with given observations leads to an optimization problem over probability space. However\, the complex geometric nature of this space prevents the direct use of standard arguments and solvers. We unravel some of the surprises that emerge in this setting and discuss potential solutions.

SUMMARY:Workshop / Seminar:Topology seminar: Canonical bases of skein algebras\, and categorification
DESCRIPTION:Abstract: For an oriented surface S\, the Kauffman bracket skein algebra of S is an algebra generated by isotopy classes of framed links in the thickened surface S x (-1\,1) modulo skein relations\, and it quantizes the SL2 character variety of S. I will review various vector space bases of the skein algebra\, and discuss the problem on the positivity of structure constants. I will spend enough time to give an elementary introduction\, and towards the end I will briefly present recently known results\, from quantum cluster algebras and mirror symmetry\, from foams\, and from quantized K-theoretic Coulomb branches. I hope to focus more on the last one\, which is based on my joint work 2505.13332 with Dylan Allegretti and Peng Shan\, which gives a monoidal categorification of the skein algebra of a genus zero punctured surface.

SUMMARY:Workshop / Seminar:THE HEREDITARY LAWS OF LARGE NUMBERS
DESCRIPTION:The celebrated theorem of Komlos (1967) establishes L^1-boundedness as a sufficient condition for a sequence of measurable functions on a probability space to contain a subsequence along which\, and along whose every further subsequence (“hereditarily”)\, the Cesaro averages converge to a “randomized mean” in the spirit of the Strong law of Large Numbers. We provide conditions not only sufficient\, but also necessary\, for this result\, as well as for the hereditary analogues of the Weak Law of Large Numbers\, of the Hsu-Robbins-Erdos Law of Large Numbers\, and of the Law of the Iterated Logarithm. \n\nJoint work with I. Berkes (Budapest) and W. Schachermayer (Vienna).

SUMMARY:Workshop / Seminar:Regularization by Common Noise for Mean Field Games and Mean Field Control
DESCRIPTION:A fundamental challenge in the theory of mean field games (MFGs) is that equilibria are generally non-unique in the absence of monotonicity assumptions. In this talk\, we establish that an infinite-dimensional multiplicative common noise restores uniqueness for generic MFGs in one spatial dimension. Furthermore\, by exploiting the connection between mean field control (MFC) and potential MFGs\, we show that this common noise regularizes the MFC value function. Based on this regularity\, we then construct optimal feedback controls for the MFC problem. This talk is based on joint work with F. Delarue.

SUMMARY:Workshop / Seminar:The optimal rate of convergence in mean field control
DESCRIPTION:I will discuss the sharp rate of convergence of the value functions of N-particle stochastic control problems to their mean field limit\, for merely Lipschitz mean field costs. For d ≥ 2\, the optimal rate is that of the empirical measures of i.i.d. samples in the 1-Wasserstein distance\, as conjectured by Daudin\, Delarue\, and Jackson\, and it persists with additive common noise. In dimension one\, this benchmark can surprisingly be beaten: cooperating particles outperform independent samples\, and the optimal exponent is 4/7\, strictly between the accuracy of independent sampling (N^{-1/2}) and that of quantization (N^{-1}). The proofs rely on a new control-theoretic technique of recoupled shadow flows and\, in dimension one\, on a Gibbs law implementing the cooperation and a Schrödinger ground-state estimate.
