Time: Friday November 4, 2011, 15:15-17:15 pm

Speaker: Xin Wang (Peking University)

Venue: Room 09 at Quan-Zhai (全斋), New location for BICMR, Peking University

Abstract: In the first part,I will give the basic kownledge of Gromov-Witten Classes ,Quantum cohomology and an application to counting rational curves on projective space.In the second part,I will give definition of cohomological field theory,and prove that tree level theories are determined by their correlation functions.
