报告题目：Gamma class in the oscillatory integrals

报告摘要：The Gamma class arises naturally in the oscillatory integral of the LG model in various settings. In particular, I will explain its role in the remodeling conjecture with descendants, and also for the mirror of toric fano varieties and beyond. This talk is based on the several joint works with Melissa Liu, Song Yu, Junxiao Wang, Peng Zhou, Yan Zhou, and Zhengyu Zong.
