Speaker: Dr. Michael Brown

Title: The Bernstein-Gel'fand-Gel'fand (BGG) correspondence

Modality: Speaker Remote, participants may join remotely or in one of the empty rooms on the 2nd floor of Parker.

Abstract: Roughly speaking, the BGG correspondence says that doing homological algebra over a polynomial ring is the same as doing homological algebra over an exterior algebra. I will discuss the BGG correspondence in detail, and I will describe an application of the BGG correspondence, due to Eisenbud--Floystad--Schreyer, to an algorithm for computing the cohomology of sheaves over projective space.
