利用随机流研究流形的可缩性

Contractibility of manifolds by means of stochastic flows

Alexandra Antoniouk, Sergiy Maksymenko

摘要:

在纸上[Probab。理论关系Fields,100(1994)417-428]李雪梅(XuemeiLi)已经证明了一个流形的矩稳定性与其基础流形的拓扑结构密切相关。特别是,她给出了充分条件上的流形$M$下,基本群$π_1 M=0$。证明了在类似的条件下,流形$M$实际上是可收缩的,即所有同伦群$π_k M$,$k\geq1$为零.

英文摘要:

In the paper [Probab. Theory Relat. Fields, 100 (1994) 417-428] Xue-Mei Li has shown that the moment stability of an SDE is closely connected with the topology of the underlying manifold. In particular, she gave sufficient condition on SDE on a manifold $M$ under which the fundamental group $π_1 M=0$. We prove that in fact under the similar conditions the manifold $M$ is contractible, that is all homotopy groups $π_k M$, $k\geq1$, vanish.
