证明了体积增长不低于5次多项式的拟顶点可迁图上的简单随机游走几乎处处有无穷多个切割时,从而有无穷多个切割点.该结论在所论情形下肯定了Benjamini,Gurel-Gurevich和Schramm在文[2011,Cutpoints and resistance of random walk paths,Ann.Probab.,39(3):1122-1136]中提出的猜想:顶点可迁图上暂留简单随机游走几乎处处有无穷多个切割点. 相似文献

1. IntroductionThe log-Sobolev inequalities on loop spaces over compact Riemannian manifolds havebeen received much attention (see [1-6]). In particular, for loop group over a compact typeLie group, by replacing pinned Wiener measure with a heat kernel measure, Driver andLohrenz[2] obtained a log-Sobolev inequality without added potential.Let G be a d-dimensional compact type Lie group with unit element e and harr measuredx. Denote by g the Lie algebra of G with an Ad(G) invariant inner … 相似文献

A stochastic holonomy along a loop obtained from the OU process on the path space over a compact Riemannian manifold is computed.
The result shows that the stochastic holonomy just gives the parallel transport with respect to the Markov connection along
the OU process on the path space 相似文献

在本文中,我们构造了一个2维完备黎曼流形;其上的布朗运动是非内向爆发的,且存在一个对应于负Levi-Civita联络的内向爆发鞅。此外,我们也考虑了布朗运动的非内向爆发。 相似文献
