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).
