Wuhan University(武汉大学);Florida State University(佛罗里达州立大学)

Fuqing Gao, Lingjiong Zhu

AI总结:

研究多维非线性Hawkes过程在维数趋于无穷时的平均场极限,证明其满足大偏差原理。

摘要:

Hawkes过程是一类简单点过程,其强度依赖于过去历史,通常是非马尔可夫的。文献中研究了各种渐近条件下Hawkes过程的极限定理。本文研究多维非线性Hawkes过程在维数趋于无穷时的渐近行为,其平均场极限是一个时间非齐次泊松过程,主要结果是关于平均场极限的大偏差原理。

英文摘要:

Hawkes processes are a class of simple point processes whose intensity depends on the past history, and is in general non-Markovian. Limit theorems for Hawkes processes in various asymptotic regimes have been studied in the literature. In this paper, we study a multidimensional nonlinear Hawkes process in the asymptotic regime when the dimension goes to infinity, whose mean-field limit is a time-inhomogeneous Poisson process, and our main result is a large deviation principle for the mean-field limit.
