GL-algebras and the Noetherianity problem (combinatorics seminar)
Karthik Ganapathy, UC San Diego
Draisma recently proved that finite length polynomial representations of the infinite general linear group GL are topologically...
Student Algebraic Geometry: Complete Intersections of Two Quadrics in Projective Space
Saket Shah
Complete intersections in projective space are, behind hypersurfaces, perhaps the easiest varieties to study, but even in simple cases can...
2024 SIAM Student Mini-Symposium in Applied Mathematics
The SIAM student chapter at the University of Michigan is hosting the 2024 SIAM Student Mini-Symposium in Applied Mathematics on September...
Algebraic Geometry Seminar: Stability conditions on surface root stacks
Yeqin Liu (University of Michigan)
Compared to varieties, vector bundles and derived categories on stacks are less understood. (Bridgeland) stability conditions are effective...
Forks and their uses (combinatorics seminar)
Tucker Ervin, University of Alabama
Mutation-finite quivers --- those mutation-equivalent to only a finite number of quivers --- are relatively well-understood objects....
AIM Seminar: Harnessing Structural Periodicity for Wave Control Toward Sensing, Harvesting, and Space Applications
Serife Tol, Mechanical Engineering, University of Michigan
The study of structural periodicity in engineered materials, such as metamaterials, phononic crystals, and metasurfaces, has opened new...
Long-time behaviors of stochastic linear-quadratic optimal control problems.
Jian Jiamin
This paper investigates the asymptotic behavior of the linear-quadratic stochastic optimal control problems. By establishing a connection...
RTG Seminar Geometry, Dynamics and Topology: Big Mapping Class Groups in Dimensions 0, 1, and 2
George Domat
We will give a gentle introduction to the world of big mapping class groups. These arise as groups of topological symmetries of:...
Operahedron Lattices (Combinatorics Seminar)
Andrew Sack, University of Michigan
Two classical lattices are the Tamari lattice on bracketings of a word and the weak order on permutations. The Hasse diagram of each of...
RTG Number Theory Seminar: The Kazhdan--Lusztig isomorphism
Alex Bauman and Calvin Yost-Wolff
Abstract:
Existence of Optimal Stationary Singular Controls and MFG Equilibria
Chuhao Sun, UM
We examine the stationary relaxed singular control problem within a multi-dimensional framework for a single agent, as well as its Mean...
AIM Seminar: Ideology-ology: Diagnostic Perspectives and Reality-Seeking Dynamical Modeling of the US Political Ecosystem
David Sabin-Miller, University of Michigan, Complex Systems
The US political arena is generally a bleak mix of distressing and aggravating, particularly in the current highly polarized climate, but...
Cyclically ordered quivers (Combinatorics Seminar)
Scott Neville, University of Michigan
Quivers and their mutations play a fundamental role in the theory of cluster algebras. We focus on the problem of deciding whether two given...
RTG Number Theory Seminar: The Kazhdan--Lusztig isomorphism, continued
Alex Bauman and Calvin Yost-Wolff
Abstract:
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...

AIM Seminar: Extreme Superposition: Models for Large-Amplitude Rogue Waves
Peter D. Miller, University of Michigan
Rogue waves or freak waves are spatially-localized disturbances of a background field that are also temporally localized. In the setting of...
