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...
