Computer Science/Discrete Mathematics Seminar I

Algorithmizing the Multiplicity Schwartz-Zippel Lemma
Prahladh Harsha
11:15am|Simonyi 101 and Remote Access

The degree mantra states that any non-zero univariate polynomial of degree at most d has at most d roots (counted with multiplicity). A generalization of this to the multivariate setting, proved by Dvir-Kopparty-Saraf-Sudan asserts that over any...

Computer Science/Discrete Mathematics Seminar II

Bounds for subsets of $\mathbb{F}_p^n \times \mathbb{F}_p^n$ without L-shaped configurations
10:30am|Simonyi Hall 101 and Remote Access

I will discuss the difficult problem of proving reasonable bounds in the multidimensional generalization of Szemerédi's theorem. Most of the first talk will be spent going over Shkredov's proof of good bounds for sets lacking corners, in preparation...

Arithmetic Groups

Profinite Completions and Representation Rigidity
Ryan Spitler
11:00am|Simonyi 101 and Remote Access

Taking up the terminology established in the first lecture, in 1970 Grothendieck showed that when two groups $(G,H)$ form a Grothendieck pair, there is an equivalence of their linear representations. For recent work showing that certain groups are...
