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.

报告人简介:曾昊智,复旦大学博士后,研究方向为toric topology。曾昊智博士与合作者给出了一类非单连通的toric origami manifolds上的Betti数和等变上同调环的组合表达公式。该结果发表在《Journal of Symplectic Geometry》上。
