主讲人简介：Changlong Zhong is an Associate Professor at the State University of New York at Albany. He graduated from the University of Southern California with a PhD in 2011 under the supervision of Thomas Geisser. He works in the field of algebraic K-theory, motivic cohomology, and cohomology of flag varieties.
讲座主题：Hecke-type algebras and Schubert calculus
讲座摘要:Hecke-type algebras originated from representation theory, combinatorics, number theory, and algebraic geometry. We will focus on their relation with Schubert calculus. These algebras are generated by the so-called divided difference operators indexed by the simple roots of a root system, and they satisfy the braid relations. These algebras provided models for the equivariant generalized cohomology of flag varieties (cohomology, K-theory and elliptic cohomology).
