Title:Universal equations for Gromov-Witten Invariants
Seminar:Department of Mathematics Colloquium
Speaker:Xiaobo Liu, University of Notre Dame
Abstract:
There are many natural cohomology classes on moduli spaces of stable curves. Reletions among such classes produce universal equations for Gromov-Witten invariants for all compact symplectic manifolds. These equations can be used to compute Gromov-Witten invariants and study the Virasoro conjecture proposed by string theoriests Eguchi, Hori, and Xiong.In this talk, I will describe the current state of the universal equations and their applications.
