报告摘要:The Peterson variety is introduced by Dale Peterson to describe the quantumcohomology rings of all the partial flag varieties. In this talk, we discuss anexplicit morphism from the Peterson variety to the Blume toric orbifold. As anapplication, we calculate the totally nonnegative part of the Peterson varietyin Lie type A and give a proof of Rietsch's conjecture.This is joint work with Hiraku Abe.
