Speaker Praise Adeyemo (University of Ibadan, Nigeria)

There are quite a number of subvarieties which can be defined to sit inside flag varieties. One of such is the family of Hessenberg varieties. In this talk, I will give combinatorial and geometric descriptions of the computation of Betti numbers of one of the class members of the family known as Springer varieties and discuss the current problem at hand.
