Topology Seminar: Countable unions of finite groups as hidden symmetries of the free group (March 28, 2024 3:00pm) https://events.umich.edu/event/114881 114881-21833726@events.umich.edu Event Begins: Thursday, March 28, 2024 3:00pm

Symmetries of a group G are encoded in the automorphism group Aut(G). "Hidden symmetries" are encoded in the abstract commensurator Comm(G). While many classes of finitely generated groups have reasonably well-understood commensurator --- for example, Comm(G) is typically a group of matrices with rational entries when G is arithmetic --- the abstract commensurator of a free group, Comm(F_2), is still somewhat mysterious. I will explain how Edgar A Bering IV and I fleshed out a topological perspective of commensurations that allowed us to show that every countable locally finite group is a subgroup of Comm(F_2).

The Kahler-Ricci flow is a fully non-linear strictly parabolic equation that deforms compact Kahler manifolds. Being non-linear, it develops finite time singularities. I will present a new singularity model of the flow and describe our efforts to find it. This is joint work with Deruelle-Sun, Cifarelli-Deruelle, and Bamler-Cifarelli-Deruelle.

In 1964, Horrocks proved that a vector bundle on a projective space splits as a sum of line bundles if and only if it has no intermediate cohomology. Generalizations of this criterion, under additional hypotheses, have been proven for other toric varieties, for instance by Eisenbud-Erman-Schreyer for products of projective spaces, by Schreyer for Segre-Veronese varieties, and Ottaviani for Grassmannians and quadrics. This talk is about a splitting criterion for arbitrary smooth projective toric varieties, as well as an algorithm for finding indecomposable summands of sheaves and modules in the more general setting of Mori dream spaces.

In this series of talks I will try to give an overview of the main issues that arise when trying to establish mod p and p-adic analogues of the theorems of Langlands, Deligne, Drinfeld and Carayol, describing the l-adic (l ≠ p) étale cohomology of the Drinfeld and Lubin-Tate towers. The methods are very different, based on perfectoid spaces, representation theory of GL2(Qp) and its inner form, as well as syntomic cohomology and the six-functor formalism due to Lucas Mann. This is based on joint work with Colmez and Niziol (for the Drinfeld tower) and Camargo (for the Lubin-Tate tower).

This will be an open discussion of ways to handle microaggressions in the classroom. We will start by briefly discussing what microaggressions are. Then we will go over some options for how to respond. The rest of the event will be practice with responding to microaggressions in small groups. We will cover both student-to-student interactions and student-to-instructor interactions. This event is open to grad students and faculty. Younger grad students are especially encouraged to attend! This event will go beyond what was discussed in teaching training, to cover the kind of interactions that hopefully don't happen often, but which may show up as instructors get more experience teaching.

Note: Sensitive topics may be covered, so if you would like a list of scenarios ahead of time or need some other accommodation in order to attend, contact Anna (annabro) or Schinella (dsouzas).

Speyer's g conjecture and Betti numbers for a pair of matroids (March 29, 2024 3:00pm) https://events.umich.edu/event/117197 117197-21838813@events.umich.edu Event Begins: Friday, March 29, 2024 3:00pm

In 2009, looking to bound the face vectors of matroid subdivisions and tropical linear spaces, Speyer introduced the g-invariant of a matroid. He proved its coefficients nonnegative for matroids representable in characteristic zero and conjectured this in general. Later, Shaw and Speyer and I reduced the question to positivity of the top coefficient. This talk will overview work in progress with Berget that proves the conjecture.

Geometrically, the main ingredient is projection away from the base of the matroid tautological vector bundles of Berget--Eur--Spink--Tseng, and initial degenerations of these. Combinatorially, it is an extension of the definition of external activity to a pair of matroids and a way to compute it using the fan displacement rule. The work of Ardila and Boocher on the closure of a linear space in (P^1)^n is a special case.

The Kuznetsov component is a very important subcategory in the derived category of coherent sheaves. In many cases, it is shown that the Kuznetsov component can control the birational geometry of Fano varieties, where the first case dates back to 2004 by Kuznetsov on cubic threefolds. After the development of a tool called stability conditions, there have been a lot of breakthroughs regarding this subcategory. Some interesting questions are raised around this topic recently, such as the geometry of the space of stability conditions on Kuznetsov components, which is known to be a complex manifold. In this talk, I will start with the definition of these notions, and give an overview of some of the latest developments in this area.

Abstract: Neurons in cortex are connected in intricate patterns, with local- and long-range connections and distance-dependent time delays for transmitting signals. In recent work, we have found that spontaneous and stimulus-driven waves of neural activity travel over these networks, sparsely modulating the spiking activity of the local network as they pass. The waves represent changes in the moment-by-moment activity state of these networks, which in turn directly shapes neuronal responses to incoming visual input and causes measurable effects in visual perception.

Understanding how the networks of cortex generate these sophisticated dynamics, however, remains an open problem. This is due, in part, to the fact that connecting the specific structure of networks to the resulting nonlinear dynamics is a difficult problem in general. Experiments suggest one mechanism for these waves could be the distance-dependent time delays due to transmitting spikes along the axons connecting neurons across these networks. Analyzing the underlying network mechanism for these waves thus represents an additional mathematical challenge, as we need to consider systems with many time delays.

In this talk, I will present recent results from my group connecting the structure of individual networks to the resulting dynamics in systems of nonlinear Kuramoto oscillators. We introduce a complex-valued approach that allows linking the precise structure of connections in the network to the spatiotemporal patterns that will occur in individual simulations. This approach allows understanding these activity patterns in terms of a modification of the eigenspectrum of the graph adjacency matrix. This, in turn, leads to analytical predictions for the precise traveling wave patterns that will emerge in these systems. Finally, I will present our latest efforts to understand computation with spatiotemporal dynamics in neural systems using these nonlinear network models.

I will discuss the growth rate of the number of elements of the mapping class group of each Nielsen-Thurston type, that is, either finite-order, reducible, or pseudo-Anosov. We approach this question from the perspective of the so-called lattice point counting problem for the mapping class group acting on Teichmuller space, which concerns the number of group elements that send a given point into a ball of radius R about another point. In the case of a closed surface of genus g, Athreya, Bufetov, Eskin, and Mirzakhani have shown that, for the whole mapping class group, this quantity is asymptotic to exp((6g-6)R) as R tends to infinity. Maher has obtained the same asymptotics for those orbit points that are translates by pseudo-Anosov elements. We consider the remaining Nielsen-Thurston types: For finite-order elements we show the associated count grows coarsely at the rate of exp((3g-3)R), that is with exactly half the exponent, and for reducible elements it grows at the rate exp((6g-7)R). In order to achieve this, we introduce a new notion of "complexity length" in Teichmuller space which has several interesting features reflecting aspects of negative curvature. Joint work with Howard Masur.

In this talk I will be speaking about the dimer model sampled on a general Riemann surface. In this setup, the dimer height function becomes additively multivalued with a random monodromy. Given a sequence of graphs approximating the conformal structure of the surface in a suitable way, the underlying sequence of height functions is expected to converge to the compactified free field on the surface. Recently, this problem was addressed by Berestycki, Laslier and Ray in the case when a Riemann surface is approximated by Temperley graphs. Using various probabilistic methods, they obtained the following universal result: given that the random walk associated with these graphs converges to the Brownian motion on the surface (in an appropriate sense), the limit of height functions exists, is conformally invariant and does not depend on a particular sequence of graphs. However, the identification of the limit with the compactified free field was missing in this result. In my recent work I am trying to fill this gap by studying the same problem from the perspective of discrete complex analysis. For this purpose, I consider graphs embedded into locally flat Riemann surfaces with conical singularities and satisfying certain local geometric conditions. In this setup I obtain an analytic description of the limit which allows to identify it with a suitable version of the compactified free field; I also prove the convergence in some non-Temperlian cases when the surface is generic. A core part of this approach is the regularity theory on t-embeddings recently developed by Chelkak, Laslier and Russkikh, as well as an analytic technique linking the problem with Quillen determinant of a family of Cauchy-Riemann operators developed by Dubédat.

Hurwitz spaces, certain finite covers of unordered configuration spaces of the plane, and their generalizations play a fundamental role in the recent flurry of remarkable work connecting topology and number theory, such as Ellenberg-Venkatesh-Westerland, Ellenberg-Tran-Westerland, Liu-Wood-Zureick-Brown, and Ellenberg-Landesman. In this talk, we will explain the approach of Ellenberg-Tran-Westerland to produce an asymptotic bound on the homology of Hurwitz spaces, starting with integrating the classical Fox-Neuwirth stratification of configuration spaces into the twisted setting. Time permitting, we will explore ways to expand this framework to study the homology of generalized Hurwitz spaces over an arbitrary curve, which has potential applications in number theory.

Mean field games (MFGs) study strategic decision-making in large populations where individual players interact via specific mean-field quantities. They have recently gained enormous popularity as powerful research tools with vast applications. For example, the Nash equilibrium of MFGs forms a pair of PDEs, which connects and extends variational optimal transport problems. This talk will present recent progress in this direction, focusing on computational MFG and engineering applications in robotics path planning, pandemics control, and Bayesian/AI sampling algorithms. This is based on joint work with the MURI team led by Stanley Osher (UCLA).

Abstract: In the last dozen years, topological methods have been shown to produce a new pathway to study arithmetic statistics over function fields, most notably in Ellenberg-Venkatesh-Westerland's work on the Cohen-Lenstra conjecture. More recently, Ellenberg, Tran and Westerland proved the upper bound in Malle's conjecture on the enumeration of function fields by studying the homology of braid groups with certain exponential coefficients. In this talk, we will give an overview of their framework and extend their techniques to study other questions in arithmetic statistics. As an example, we will demonstrate how this extension can be used to study character sums of the resultant of monic squarefree polynomials over finite fields, answering and generalizing a question of Ellenberg and Shusterman, and Malle's conjecture for function fields with prescribed ramification.

In 1966, Mark Kac posed the famous question “Can you hear the shape of a drum?” Mathematically, this amounts to recovering the geometry of a Riemannian manifold from knowledge of its Laplace spectrum. In the case of strictly convex and smooth bounded planar domains, the problem is very much open. One technique for studying the inverse spectral problem is via the wave trace, a distribution with singular support contained in the length spectrum. The length spectrum is the collection of lengths of closed geodesics, which for planar domains are just periodic billiard orbits. A dual object to study is the resolvent (of the Laplacian), whose trace asymptotics are related via the Payley-Wiener theorem to singularities of the wave trace. In this talk, we introduce the Balian-Bloch-Zelditch method of constructing a parametrix for the resolvent trace via layer potentials. The result is an oscillatory integral to which one can apply the method of stationary phase. A novel feature is the organization of stationary phase coefficients by using graph theory and Feynman diagrams. The resulting formulas can be used to match Maslov indices of orbits and produce cancellations in the wave trace, which shows that the length spectrum and the Laplace spectrum are inherently distinct objects, at least insofar as the wave trace is concerned.

The nth symbolic power P^(n) of P can be geometrically interpreted as the set of regular functions of R that vanish to order n at the generic point of V(P). With this geometric insight, if P\subseteq Q are prime ideals within the non-singular locus of Spec(R), then the Local Zariski-Nagata Theorem states P^(n)\subseteq Q^(n) and translates into a natural criterion for vanishing order along non-singular algebraic sets: functions vanishing to order n at the generic point of V(P) must vanish to order at least n at the generic point of V(Q).

However, when Q is a singular prime, the behavior of vanishing orders becomes less intuitive. Huneke, Katz, and Validashti's Uniform Chevalley Lemma rectifies this scenario by providing a constant C, depending on Q, such that if a function vanishes to order Cn at the generic point of V(P), then it must vanish to order at least n at the generic point of V(Q).

In our exploration of uniformity in Noetherian rings, we introduce the Uniform Izumi-Rees Property, which eliminates the dependency of the constant C on Q in the Uniform Chevalley Lemma. Furthermore, we establish that normal domains essentially of finite type over a field enjoy the Uniform Izumi-Rees Property.

Abstract: Turbulent particle-laden flows give rise to spatial heterogeneity (e.g. clustering) characterized by two-point statistics. Most coarse-grained (i.e. two fluid) models only solve for one-point moments, limiting reproduction of important two-phase flow statistics. In this talk, we present set of equations describing the evolution of these flows that include fluctuating components of filtered fields --- a description of the level of clustering present in these flows. For dilute heavy particles settling in homogeneous isotropic turbulence, the averaged filtered drag and filtered Reynolds-stress like term that dictates enhanced settling is correlated to this description of volume fraction fluctuation. A data-driven approach that efficiently traverses parameter space in direct numerical simulations to inform closures is proposed, providing both descriptive insights and directions for future modeling. Further, a numerical crossflow experiment is proposed, yielding several advantages over traditional forced homogeneous isotropic turbulence for the study of turbulent particle-laden flows. The filtered volume fraction is shown to be valuable in that it may enable better fits for unclosed quantities related to particle drag and particle-phase momentum flux in coarse-grained simulations.

We first define some preliminaries, such as the gamma function, beta function, time convolution. We include some useful properties, some with proof. Then, we introduce the Riemann-Liouville (RL) fractional integral, and use it to define the RL fractional derivative. We show that the RL derivative has some unsatisfactory properties, and thus define the Caputo fractional time derivative to rectify these short comings. We then introduce the Mittag-Leffler function as a solution operator for some simple fractional differential equations. Time permitting, we may also briefly discuss the use of the Caputo derivative in the doubly non-local Cahn Hilliard Equation.

A prediction market is a market where people can trade based on the outcomes of future events. It is widely used in sports games, elections, and the pricing of digital options. In math finance, prediction markets can be modeled by the so-called win martingales, continuous time martingales that end up with Bernoulli distributions. In this talk, choosing specific divergences as objective functionals, we will solve a class of optimal win martingale. In some cases, we will get explicit formulas of optimizers, and make connections between Schrödinger and filtering problems. Based on the joint work with Julio Backhoff.

Hilbert’s sixth problem asks for a mathematically rigorous justification of the macroscopic laws of statistical physics from the microscopic laws of dynamics. The classical setting of this problem asks for the justification of Boltzmann’s kinetic equation from Newtonian particle dynamics. This justification has been proven for short times, starting with the work of Lanford in 1975, but its long time justification remains one of the biggest open problems in kinetic theory.

If classical colliding particles are replaced with interacting waves, one formally obtains what is known as "wave kinetic theory”, which is sometimes also called "wave turbulence theory". This theory of statistical physics for waves has been developed, starting in the late 1920s, for wave systems that arise in various scientific disciplines like many-particle quantum physics, oceanography, climate science, etc. The central mathematical problem there is also the justification of a kinetic equation, known as the wave kinetic equation, starting from the Hamiltonian PDE that governs the corresponding microscopic system. In this talk, we shall describe the state of the art of this problem, leading to a most recent joint work with Yu Deng (USC), in which we give the first instance of a long time justification of a nonlinear (particle or wave) collisional kinetic limit.

Abstract: The immersed boundary (IB) method is a framework for modeling systems in which an elastic structure interacts with a viscous incompressible fluid. The fundamental feature of the IB approach to such fluid-structure interaction (FSI) problems is its combination of an Eulerian formulation of the momentum equation and incompressibility constraint with a Lagrangian description of the structural deformations and resultant forces. In conventional IB methods, Eulerian and Lagrangian variables are linked through integral equations with Dirac delta function kernels, and these singular kernels are replaced by regularized delta functions when the equations are discretized for computer simulation. This talk will focus on three related extensions of the IB method. I first detail an IB approach to structural models that use the framework of large-deformation nonlinear elasticity. I will focus on efficient numerical methods that enable finite element structural models in large-scale simulations, with examples focusing on models of the heart and its valves. Next, I will describe an extension of the IB framework to simulate soft material failure using peridynamics, which is a nonlocal structural mechanics formulation. Numerical examples demonstrate constitutive correspondence with classical mechanics for non-failure cases along with essentially grid-independent predictions of fluid-driven soft material failure. Finally, I will introduce a reformulation of the IB large-deformation elasticity framework that enables accurate and efficient fluid-structure coupling through a version of the immersed interface method, which is a sharp-interface IB-type method. Computational examples demonstrate the ability of this methodology to simulate a broad range of fluid-structure mass density ratios without suffering from artificial added mass instabilities, and to facilitate subgrid contact models. I will also present biomedical applications of the methodology, including models of clot capture by inferior vena cava filters.

Bio: Boyce Griffith is a Professor in the Department of Mathematics and of Biomedical Engineering at the University of North Carolina, where he is also an Adjunct Professor of Applied Physical Sciences and Associate Chair for Research in the Department of Mathematics. His research group focuses on the development and application of numerical methods for simulating fluid-structure interaction with a particular focus on models of the heart and its valves. Their core approach is based on extensions of the immersed boundary method fluid-structure interaction.

A sequence of positive real numbers a_1, a_2, ..., a_n, is log-concave if a_i^2 >= a_{i-1}a_{i+1} for all i ranging from 2 to n-1. Log-concavity naturally arises in various aspects of mathematics, each characterized by different underlying mechanisms. Examples range from inequalities that are readily provable, such as the binomial coefficients a_i = \binom{n}{i}, to intricate inequalities that have taken decades to resolve, such as the number of forests a_i in a graph G with i edges. It is then natural to ask if it can be shown that the latter type of inequalities is intrinsically more challenging than the former. In this talk, we provide a rigorous framework to answer this type of questions, by employing a combination of combinatorics, complexity theory, and geometry. This is a joint work with Igor Pak.

Utilizing game theory and deep learning to find optimal policies for large number of agents (April 17, 2024 4:00pm) https://events.umich.edu/event/112183 112183-21828569@events.umich.edu Event Begins: Wednesday, April 17, 2024 4:00pm

In many real-life policy making applications, the principal (i.e., governor or regulator) would like to find optimal policies for a large population of interacting agents who optimize their own objectives in a game theoretical framework. With the motivation of finding optimal policies for large populations, we start with introducing continuous time Stackelberg mean field game problem between a principal and a large number of agents. In the model, the agents in the population play a non-cooperative game and choose their controls to optimize their individual objectives while interacting with the principal and the other agents in the society through the population distribution. The principal can influence the resulting mean field game Nash equilibrium through incentives to optimize her own objective. Therefore, Stackelberg mean field game problems are by their nature bi-level problems where we have an optimal control problem at the principal level and a Nash equilibrium problem at the population level. This bi-level nature creates many efficiency challenges for the implementation of numerical approaches. For this reason, we will analyze how to rewrite this bi-level problem as a single-level problem and propose a deep learning approach to solve it. Then we will briefly discuss the convergence of the numerical solution where we utilize the single level problem to the solution of the original problem. We will conclude by demonstrating some applications such as the systemic risk model for a regulator and many banks and an optimal contract problem between a project manager and a large number of employees.

LPs with heterogeneous characteristics choose optimal liquidity positions subject to uncertainty regarding the size of exogenous incoming transactions and the prices of assets in a centralized market. They engage in a game among themselves, and the resulting liquidity distribution determines the exchange rate dynamics and potential arbitrage opportunities of the pool. We calibrate the distribution of LP characteristics based on Uniswap data and the equilibrium strategy resulting from this mean-field game produces pool exchange rate dynamics and liquidity evolution consistent with observed pool behavior. We subsequently introduce Maximal Extractable Value (MEV) bot attackers and develop a Stackelberg game between LPs and bots. This results in more accurate simulated pool exchange rate dynamics and stronger predictive power regarding the evolution of the pool liquidity distribution.

Joint work with Erhan Bayraktar and Asaf Cohen
