Analysis Seminar

Stochastic quantization equations
Hao Shen
4:00pm|S-101

Stochastic quantization equations are evolutionary PDEs driven by space-time white noises. They are proposed by physicists in the 80s as the natural dynamics associated to the (Euclidean) quantum field theories. We will discuss the recent progress...

Geometric Structures on 3-manifolds

Free group Cayley graph and measure decompositions
2:00pm|S-101

I will talk about convex-cocompact representations of finitely generated free group $F_g$ into $\mathrm{PSL}(2,\mathbb C)$. First I will talk about Schottky criterion. There are many ways of characterizes Schottky group. In particular, convex hull...

Computer Science/Discrete Mathematics Seminar II

Minkowski sums, mixed faces and combinatorial isoperimetry
Karim Adiprasito
10:30am|S-101

I want to sketch some algebraic and geometric tools to solve a variety of extremal problems surrounding Minkowski sums of polytopes and colorful simplicial depth.

Members’ Seminar

Mock and quantum modular forms
Amanda Folsom
2:00pm|S-101

Mock modular forms were first formally defined in the literature by Zagier in 2007, though their roots trace back to the mock theta functions, curious power series described by Ramanujan in his last letter to Hardy in 1920. As the overarching theory...

Computer Science/Discrete Mathematics Seminar I

The deterministic communication complexity of approximate fixed point
Omri Weinstein
11:15am|S-101

We study the two-party communication complexity of the geometric problem of finding an approximate Brouwer fixed-point of a composition of two Lipschitz functions $g \circ f$, where Alice knows $f$ and Bob knows $g$. We prove an essentially tight...

Joint IAS/Princeton University Number Theory Seminar

Vanishing cycles and bilinear forms
Will Sawin
4:30pm|S-101

In joint work with Emmanuel Kowalski and Philippe Michel, we prove two different estimates on sums of coefficients of modular forms---one related to L-functions and another to the level of distribution. A key step in the argument is a careful...

Joint IAS/Princeton University Symplectic Geometry Seminar

Spectral invariants for contactomorphisms of prequantization bundles and applications
Frol Zapolsky
10:30am|S-101

I'll outline the construction and computation of a Floer homology theory for contact manifolds which are prequantization spaces over monotone symplectic manifolds, and of the spectral invariants resulting therefrom, and present some applications...

Mathematical Conversations

Quantum chaos and eigenvalue statistics
6:00pm|Dilworth Room

One of the outstanding insights obtained by physicists working on "Quantum Chaos" is a conjectural description of local statistics of the spectrum of the Laplacian on a Riemannian surface according to crude properties of the dynamics of the geodesic...

Computer Science/Discrete Mathematics Seminar II

The singularity of symbolic matrices
10:30am|S-101

While this lecture is a continuation of the lecture from last Tuesday, I will make it self contained. The main object of study of this talk are matrices whose entries are linear forms in a set of formal variables (over some field). The main problem...
