Doob分解定理的推广

Generalization of Doob decomposition Theorem

Nicholas Gonchar

摘要:

本文引入了关于等价测度凸集的局部正则上鞅的概念,并证明了它在离散情形下的任意Doob分解。这个定理是著名的Doob分解在关于等价测度的凸集的上鞅情形的推广。

英文摘要:

In the paper, we introduce the notion of a local regular supermartingale relative to a convex set of equivalent measures and prove for it an optional Doob decomposition in the discrete case. This Theorem is a generalization of the famous Doob decomposition onto the case of supermartingales relative to a convex set of equivalent measures.
