报告内容:

The hard edge Pearcey process is universal in random matrix theory andmany other stochastic models. In this talk, we consider gap probabilityfor the thinned/unthinned hard edge Pearcey process over the interval (0,s). By working on the relevant Fredholm determinants, we obtain anintegral representation of the gap probability via a Hamiltonian related asystem of coupled differential equations and the large gap asymptotics.Moreover,   we also establish asymptotic statistical properties of thecounting function for the hard edge Pearcey process. Based on jointworks with Dan Dai, Shuai-Xia Xu and Luming Yao.
