The Structure of 2D field Theories


Speaker: Constantin Teleman, Cambridge University
Location: 2112 MSB

In this talk, I will explain how the Mumford conjecture (proved by Madsen and Weiss) leads to a structure formula for 2-dimensional Cohomological Field Theories with semi-simple underlying algebra. This implies a conjecture of Givental's on the "higher genus reconstruction" of Gromov-Witten invariants.
