$G$ -鞅的首中时性质

Properties of hitting times for $G$-martingale

Yongsheng Song

摘要:

本文研究了$G$ -鞅和停止过程的首中时的性质。证明了$G$ -鞅的停止过程仍然是$G$ -鞅,并证明了一类包含$G$ -布朗运动的$G$ -鞅的首中时是拟连续的.作为应用,我们改进了[Song 10]中的$G$ -鞅表示定理.

英文摘要:

In this article, we consider the properties of hitting times for $G$-martingale and the stopped processes. We prove that the stopped processes for $G$-martingales are still $G$-martingales and that the hitting times for a class of $G$-martingales including $G$-Brownian motion are quasi-continuous. As an application, we improve the $G$-martingale representation theorems in [Song10].
