10:30am|West Bldg. Lect. Hall

The polynomial Bogolyubov-Ruzsa conjecture which aims to quantify the amount of additive structure in dense subsets of abelian groups is one of the central conjectures in additive combinatorics which has recently been shown to have various...

Cool with a Gaussian: an \(O^*(n^3)\) volume algorithm

Santosh Vempala

11:15am|West Bldg. Lect. Hall

Computing the volume of a convex body in n-dimensional space is an ancient, basic and difficult problem (#P-hard for explicit polytopes and exponential lower bounds for deterministic algorithms in the oracle model). We present a new algorithm, whose...
