OIST Representation Theory Seminar
2021年9月28日 (火) 16:30 〜 17:30
Speaker: Hankyung Ko, Uppsala University
Title: Bruhat orders and Verma modules
Abstract: The Bruhat order on a Weyl group has a representation theoretic interpretation in terms of Verma modules. The talk concerns resulting interactions between combinatorics and homological algebra. I will present several questions around the above realization of the Bruhat order and answer them based on a series of recent works, partly joint with Volodymyr Mazorchuk and Rafael Mrden.
