有限马氏可加过程可加分量密度的一个局部极限定理

A local limit theorem for densities of the additive component of a finite Markov Additive Process

Loïc Hervé, James Ledoux

摘要:

本文研究了中心马尔可夫可加过程$\{(X_t,Y_t)\}_{t\in\T}$,其中驱动马尔可夫过程$\{X_t\}_{t\in\T}$具有有限状态空间.在适当的条件下,给出了给定$X_0$的$t^{-1/2}Y_t$的概率分布的绝对连续部分的密度的局部极限定理.收敛的收敛速率和矩条件是相对于独立同分布情况的预期条件。本文简述了有限跳过程局部时的联合分布的一个应用。

英文摘要:

In this paper, we are concerned with centered Markov Additive Processes $\{(X_t,Y_t)\}_{t\in\T}$ where the driving Markov process $\{X_t\}_{t\in\T}$ has a finite state space. Under suitable conditions, we provide a local limit theorem for the density of the absolutely continuous part of the probability distribution of $t^{-1/2}Y_t$ given $X_0$. The rate of convergence and the moment condition are the expected ones with respect to the i.i.d case. An application to the joint distribution of local times of a finite jump process is sketched.
