报告题目：On the geometry of regular Hessenberg varieties
报告摘要: Regular Hessenberg varieties are a family of subvarieties of the full flag variety G/B. This family contains the flag variety, Peterson variety and perutohedral variety. This subject makes connections between representation theory, combinatorics, algebraic geometry and algebraic topology. In this talk we discuss the cohomology groups of structure sheaves on regular Hessenberg varieties and the degree of regular Hessenberg varieties under their Plücker embeddings. This is joint work with Hiraku Abe and Naoki Fujita.
