报告内容:

The Pearcey kernel is a classical and universal kernel arising from random matrix theory, which describes the local statistics of eigenvalues when the limiting mean eigenvalue density exhibits a cusp-like singularity. It appears in a variety of statistical physics models beyond matrix models as well.

 In this talk, we consider the Fredholm determinant associated with the classical Pearcey kernel. Based on a steepest descent analysis for a 3x3 matrix-valued Riemann-Hilbert problem, we obtain asymptotics of the Fredholm determinant, which is also interpreted as large gap asymptotics in the context of random matrix theory. This is a joint work with Shuai-Xia Xu and Lun Zhang.
