马氏过程的群作用分解

A decomposition of Markov processes via group actions

Ming Liao

摘要:

本文研究了一般马尔可夫过程在流形上的不变量在李群作用下分解为径向部分(横截于轨道)和角部分(沿轨道)的问题。证明了给定一条径向路径,条件角部分是齐性空间中的非齐性\levy过程,得到了这类过程的一个表示,从而将欧氏布朗运动的斜积推广到一般情形.

英文摘要:

We study a decomposition of a general Markov process in a manifold invariant under a Lie group action into a radial part (transversal to orbits) and an angular part (along an orbit). We show that given a radial path, the conditioned angular part is a nonhomogeneous \levy process in a homogeneous space, we obtain a representation of such processes, and as a consequence, we extend the well known skew-product of Euclidean Brownian motion to a general setting.
