Abstract

The Pearcey process is a universal point process in random matrix theory. In this paper, we study the generating function of the Pearcey process on any number $m$ of intervals. We derive an integral representation for it in terms of a Hamiltonian that is related to a system of $6m+2$ coupled nonlinear equations. We also obtain asymptotics for the generating function as the size of the intervals get large, up to and including the constant term. This work generalizes some recent results of Dai, Xu and Zhang, which correspond to $m=1$.

论皮尔斯过程的生成函数

皮尔斯过程是随机矩阵理论中的一个普适点过程。本文研究了任意数$m$区间上的peararcey过程的生成函数。我们用哈密顿函数的形式推导了它的一个积分表示，这个哈密顿函数与一个$ 600 + $ 2耦合非线性方程的系统有关。我们也得到了生成函数的渐近性，当区间的大小变大，直到并包括常数项。本文推广了Dai, Xu和Zhang最近的一些结果，这些结果对应于$m=1$。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
