临界维数下布朗单的重点

Multiple points of the Brownian sheet in critical dimensions

Robert C. Dalang, Carl Mueller

摘要:

众所周知,当$(k-1)d>2kN$为$N$ -参数时,$d$ -维布朗单没有$k$ -重点,而当$(k-1)d<2kN$为$(k-1)d<2kN$时,则有这样的点.我们完成了对$k$ -重点存在性的研究,表明在$(k-1)d=2kN$的临界情况下,存在a. s.无$k$ -重点。

英文摘要:

It is well known that an $N$-parameter $d$-dimensional Brownian sheet has no $k$-multiple points when $(k-1)d>2kN$, and does have such points when $(k-1)d<2kN$. We complete the study of the existence of $k$-multiple points by showing that in the critical cases where $(k-1)d=2kN$, there are a.s. no $k$-multiple points.
