Computer Science/Discrete Mathematics Seminar I

Non-unique games over compact groups and orientation estimation in cryo-EM
Amit Singer
11:15am|S-101

Let $G$ be a compact group and let $f_{ij}\in L_2(G)$ be bandlimited functions. We define the Non-Unique Games (NUG) problem as finding $g_1\ldots,g_n\in G$ to minimize $\sum_{i,j=1}^n f_{ij}(g_i g_j^{-1})$. We devise a relaxation of the NUG problem...

Members’ Seminar

Counting Galois representations
Frank Calegari
2:00pm|S-101

One of the main ideas that comes up in the proof of Fermat's Last Theorem is a way of "counting" 2-dimensional Galois representations over $\mathbb Q$ with certain prescribed properties. We discuss the problem of counting other types of Galois...

Homological Mirror Symmetry Reading Group

A proof of Gamma conjecture in some cases via mirror symmetry
Hiroshi Iritani
10:45am|West Building Lecture Hall

I will discuss Gamma conjecture and its proof in some examples (such as complete intersections in toric varieties) using mirror symmetry. Specifically, I will talk about the B-model $D$-module associated with a LG model, Dubrovin conjecture, and...
