摘要

I will describe how to compute oscillatory integrals in the LG mirror of a toric variety, producing the quantum cohomology central charge. In particular, I will explain two different methods: solving the GKZ equations and Fourier transforms. Such computation, combined with homological mirror symmetry, gives a proof of the Gamma II conjecture for toric Fanos. This work is based on the joint works with Peng Zhou, Konstantin Aleshkin and Junxiao Wang.
