Computer Science/Discrete Mathematics Seminar I

Graphs, CSPs and Codes
Madhu Sudan
11:00am|Simonyi 101 and Remote Access

A sparsification of a structure, with respect to a class of queries, produces a compressed representation of the structure while answering every query in the class approximately correctly. The seminal example of sparsification is "graph...

Members' Colloquium

Recent Progress on the Problem of Compact Quotients
2:00pm|Simonyi 101 and Remote Access

The so-called Problem of Compact Quotients asks for which homogeneous spaces G/H there exists a discrete subgroup Gamma of G such that Gamma\G/H is a compact manifold. We will discuss this problem, and describe recent progress on it arising from...

Computer Science/Discrete Mathematics Seminar II

Parallel Repetition for 3-Player XOR Games
10:30am|Simonyi Hall 101 and Remote Access

In a $3$-$\mathsf{XOR}$ game $\mathcal{G}$, the verifier samples a challenge $(x,y,z)\sim \mu$ where $\mu$ is a probability distribution over $\Sigma\times\Gamma\times\Phi$,  and a map $t\colon \Sigma\times\Gamma\times\Phi\to\mathcal{A}$ for a...

Zeta and Multizeta for Function Fields
Dinesh Thakur
4:30pm|Simonyi 101 and Remote Access

We will describe emerging understanding of the structures related to the arithmetic of Zeta and Multizeta values for function fields through various results and conjectures.

Condensed Learning Seminar

Étale Hyperdescent
2:30pm|Princeton University, Fine Hall 314

Introduce the notion of hypersheaf and discuss its basic properties and equivalent characterizations. In particular, discuss the notions of homotopy and cohomological dimensions and their relation to hyperdescent. Sketch the proof of the fact for...

Joint IAS/PU Analysis Seminar

Generalized Cylinder Limits of Ricci Flow Singularities
Natasa Sesum
2:30pm|Simonyi Hall 101 and Remote Access

We study multiply warped product geometries MN:=Bn×Fn1×···×FnA 

g = g_B + \sum_{a=1}^A v_a^2 g_{F^{n_a}} and show that for an open set of initial data within multiply warped product geometries the Ricci flow starting at any of those develops...
