报告摘要:In this series of two talks, we study the Toda lattice hierarchy from the viewpoints of Frobenius manifold and consider its applications in the computations of Gromov-Witten invariants of P^1 and GUE correlators. In particular, in the first talk, we review Dubrovin--Zhang's loop equation for the P^1 Frobenius manifold and use it to solve an open question regarding the degree zero Gromov-Witten invariants of a smooth curve.
In this second talk, we continue the previous discussions and consider the application of Dubrovin--Zhang's loop equation in the computation of the GUE correlators. Two new proofs of a theorem of Dubrovin will be given.
