One of the major open problems in computer science to determine the exponent of matrix multiplication — the smallest number \omega such that two n-by-n matrices can be multiplied using n^{\omega +o(1)} arithmetic operations. While it is popularly conjectured that \omega = 2, we seem to be far from a proof (or disproof) of this.

In this talk I will discuss this problem in the context of the group-theoretic approach of Cohn and Umans. After giving background on this approach, I will highlight some open problems in additive combinatorics which could potentially yield \omega = 2, and discuss some recent progress towards these problems.


This seminar will take place in person (DC 2568) and on Zoom.
