Colloquium: Dr. Hannah Larson- Cohomology of moduli spaces of curves
University of California Berkeley
Abstract: The moduli space M_g of genus g curves (or Riemann surfaces) is a central object of study in algebraic geometry. Its cohomology is...
Student Number Theory: The local Langlands correspondence for toral supercuspidal representations

The local Langlands correspondence conjectures a finite-to-one map from the isomorphism classes of smooth irreducible representations of a...
Algebraic Geometry Seminar: Brill-Noether theory of special curves
Hannah Larson (UC Berkeley)
Brill-Noether theory studies the maps of curves C to projective spaces. The classical Brill-Noether theorem (established by work of...
RTG Geometry, Topology & Dynamics: LARGE DEVIATIONS AND APPLICATIONS IN HOMOGENEOUS DYNAMICS
Taehyeong Kim (Brandeis)
The Birkhoff Ergodic Theorem can be seen as a dynamical version of the law of large numbers. A natural question is how quickly the measure...
Probability and Analysis Seminar: On Beck–Fiala and Komlós Conjectures
Nikhil Bansal (University of Michigan)
A conjecture of Komlós states that the discrepancy of any collection of unit vectors is O(1), i.e., for any matrix A with unit columns,...
A variational approach to portfolio choice.
Emmet Lawless
In this talk we propose a calculus of variations approach to an optimal consumption problem with isoelastic preferences over an infinite...
AIM Seminar: Leveraging data, physical models, and the Koopman operator to make soft robots more capable
Dan Bruder (University of Michigan, Mechanical Engineering)
Abstract: Soft robots are able to safely interact with delicate objects, absorb impacts without damage, and adapt to the shape of their...
A probabilistic bijection for non-attacking fillings (Combinatorics Seminar)
Olya Mandelshtam -- University of Waterloo

Sam Payne
Crash course on nonarchimedean geometry.
LCIT: F25 Meeting 2
Establishing a common understanding of equitable teaching
We'll (re)read parts of the MAA Instructional Practices Guide (see link below). We'll focus on the last section, the cross-cutting...
Colloquium: Lizhen Ji - The Unity of Mathematics Through the Uniformization Theorem
University of Michigan
The uniformization theorem is one of the most significant results in mathematics, with a deceptively simple statement familiar to many:...
Algebraic Geometry Seminar: Shioda's conjecture on unirationality
Ben Church (Stanford University)
In characteristic zero, Castelnuovo proved that a unirational surface is rational. In positive characteristic, this fails. We discuss the...
Some New Perspectives on Kyle-Back Insider Trading Problems
Jianfeng Zhang/USC
A Kyle-Back model consists of three types of agents trading on an asset: 1) a (large) population of noise traders, who are non-strategic and...

Algebraic Geometry Learning Seminar: Nonarchimedean F-bundles
Ying Wang
Explain the definition of a nonarchimedean F-bundle, as well as operations on F-bundles, symmetries of F-bundles, and maximal/overmaximal...
Normalization effects on deep neural networks and deep learning for scientific problems.
Kostas Spiliopoulos/BU
We study the effect of normalization on the layers of deep neural networks. A given layer i with N_{i} hidden units is normalized by...
Algebraic Geometry Learning Seminar: Nonarchimedean A-model F-bundles
Gleb Terentiuk
Explain the definition of the nonarchimedean A-model F-bundle, focusing on the case of varieties defined over an algebraically closed field.
IBL Lunch
Come talk about teaching with IBL, interactive, and other active teaching methods over lunch. Bring teaching anecdotes, thoughts, and your...
Solving dynamic portfolio selection problems via score-based diffusion models
Ahmad Aghapour/ UM
In this paper, we tackle the dynamic mean-variance portfolio selection problem in a modelfree manner, based on (generative) diffusion...
GEOMETRY SEMINAR: Non-negative curvature on vector bundles over homotopy spheres.
K. Shankar (James Madison U)
The seminal theorem of Cheeger and Gromoll characterizes open manifolds of non-negative sectional curvature by showing that any such...

Explain the decomposition theorems for F-bundles.
Probability and Analysis Seminar: Quantum Remez inequality for fast query learning of d-local Hamiltonians
Alexander Volberg (Michigan State University)
How to learn a 2^n times 2^n matrix by asking approximately log n questions? Of course there is no way. But if we know the matrix is a...
