摘要
本文讨论非退化扩散过程的极性,得到了几个较好的充分条件,它可看作[1]的进一步深化。此外,我们将这些结果用来研究两个独立的非退化扩散过程的相交性,得到了一些有意思的结果。
In this paper, we study the polarity of nondegenerate diffusion processes X(t). Several sufficient conditions for P(X(E) F 0) =0 and P(X-1(F)0) = 0 is obtained which are better than the results in [1]. Furthermore, we study the intersection for two independent nondegenerate diffusion processes and obtain several interesting results.
