|Title:||Quantum cohomology of flag varieties|
|Date:||Wed, Nov 16, 2011, 15:30 - 17:00|
|Place:||Seminar Room B|
In this talk, I will give a brief introduction to the quantum cohomology of flag varieties first. Then I will show that a variety of genus zero, three-pointed Gromov-Witten invariants coincide with certain
classical intersection numbers, which was proved by studying the relationship between the quantum cohomology of complete and partial flag varieties. Some related topics, such as K-theoretic Gromov-Witten invariants and the homology of affine Grassmannians, may also be referred at the end of my talk.
