RTG Number Theory Seminar: Coherent sheaves
Jialiang Zou
Abstract: We will discuss coherent sheaves on projective space (P^n), flag varieties (G/B), base affine space (G/U), and its closure...
Classifying Hyperbolic Ergodic Stationary Measures on K3 Surfaces with Large Automorphism Groups
Megan Roda, University of Chicago
Let X be a K3 surface. Consider a finitely supported probability measure $\mu$ on Aut(X) such that $\Gamma_{\mu} = \langle Supp(\mu)\rangle...
Graph orientations and Euler characteristics
Bailee Zacovic
There is a fruitful interaction between quantum field theory and enumerative graph theory. In this talk, we introduce half-edge labeled...
ISRMT Seminar: How to represent a function in a quantum computer?
Michel Alexis (Hausdorff Center for Mathematics)
Quantum Signal Processing (QSP) is an algorithmic process by which one represents a signal $f:[0,1] \to (-1,1)$ as the upper left entry of a...
ISRMT Seminar: Non-Hermitian orthogonality in the q^(Volume) tiling model
Ahmad Barhoumi (KTH)
Consider a hexagon overlayed on a regular triangular grid, where the equilateral triangles have sidelength 1. A "lozenge" is a...
Colloquium Seminar: Chaotic spectral behavior in random graphs
Theo McKenzie (Stanford)
General heuristics suggest that quantum chaotic systems (such as manifolds with ergodic geodesic flow) exhibit the spectral statistics of...
LoG(M) Poster Presentation
Come learn about the research outcomes of this semester’s UM Lab of Geometry - LoG(M) (course MATH 440). Our featured projects are the...
Algebraic Geometry Seminar: Cycles on abelian 2n-folds of Weil type from secant sheaves on abelian n-folds
Eyal Markman (University of Massachusetts Amherst)
In 1977 Weil identified a 2-dimensional space of rational classes of Hodge type (n,n) in the middle cohomology of every 2n-dimensional...
Sequential optimal contracting in continuous time
Guillermo Alvarez, UM
In this talk I will present a principal-agent problem in continuous time with multiple lump-sum payments (contracts) paid at different...
Math LCIT Discussion
In the Math LCIT, individuals interested in inclusive teaching in mathematics meet to discuss topics related to this subject. Details of...
Scattering Diagram Combinatorics and Generalized Positivity -- Combinatorics Seminar
Amanda Burcroff, Harvard University
Cluster algebras are celebrated for their intriguing positivity properties. Two distinct proofs of this positivity have emerged: one through...
Stochastic Optimal Transport and the Stefan Problem
Raymond Chu, UCLA
We consider an optimal transport problem driven by a Lévy process with long-range jumps, aiming to minimize a cost functional that depends...
Multilevel Approximation Schemes for Value-at-Risk and Expected Shortfall
Azar Louzi/ Université Paris Cité
Evaluating the risk associated to a portfolio is important to...
An H-theorem for a conditional McKean-Vlasov process related to interacting diffusions on regular trees.
Kevin Hu, Brown
Conditional McKean-Vlasov equations (CMVE) are nonlinear stochastic processes with applications to mean-field games with common noise,...
On the mean-field limit of diffusive games through the master equation: extreme value analysis
Nikolaos Kolliopoulos/ UM
We consider an N-player game where the players control the drifts of their diffusive states which have no interaction in the noise terms....
