摘要（Abstract） 

Virasoro conjecture is one of the most fascinating conjecture in Gromov-Witten theory, which is introduced by Eguchi-Hori-Xiong. It state that the Gromov-Witten potential Z is a solution of a sequence of nonlinear differential equation: L_k(Z)=0, k>=-1. And L_k satisfies the following Virasoro relation [L_m, L_n]=(m-n)L_{m+n}

In this talk, I will give a survey on Virasoro conjecture. I will also talk about the explicit  form of Virasoro constraints on FJRW theory and prove it in some simple case, base on the joint work with Yefeng Shen.
