Galois Representations and Automorphic Forms Seminar

Completed Cohomology of Shimura Curves and a p-Adic Jacquet-Langlands Correspondence
James Newton
2:15pm|S-101

In this talk, I will describe a construction of a geometric realisation of a p-adic Jacquet-Langlands correspondence for certain forms of GL(2) over a totally real field. The construction makes use of the completed cohomology of Shimura curves, and...

Bypassing UGC From Some Optimal Geometric Inapproximability Results
Rishi Saket
10:30am|S-101

The Unique Games conjecture (UGC) has emerged in recent years as the starting point for several optimal inapproximability results. While for none of these results a reverse reduction to Unique Games is known, the assumption of bijective projections...

Members’ Seminar

Recursively Applying Constructive Dense Model Theorems and Weak Regularity
2:00pm|S-101

Green and Tao [GT] used the existence of a dense subset indistinguishable from theprimes under certain tests from a certain class to prove the existence of arbitrarily longprime arithmetic progressions. Tao and Ziegler [TZ] showedsome general...

Computer Science/Discrete Mathematics Seminar I

Fast Random Projections
Edo Liberty
11:15am|S-101

The Johnson-Lindenstrauss lemma (also known as Random Projections) states that any set of n points in Euclidian space can be embedded almost isometrically into another Euclidian space of dimension O(log(n)). The talk will focus on the efficiency of...

Analysis/Mathematical Physics Seminar

Generalized Kepler Problems
2:00pm|S-101

For many elegant mathematical examples, one can 1) find theories behind them, 2) understand why they exist in the first place, 3) explore the consequences in math and physics. If one takes the Euler number as such an example, then the theory behind...
