摘要
设X^(2.d)(t),(t∈R^+~2)是初值为x∈R^d的两参数d维Ornstein-Uhlenbeck过程,M_k为X^(2.d)(t)的k(≥2)重时集;当4k>(k-1)d时,文[1]得到了: 本文进一步获得了:
Let X2,d(t) (t R2+ ) be the two - parameter d dimension Ornstein-Uhlenbeck process atX2,d(0)=x(xRd), Mk be the k multiple time set of X2,d(t), if 4k>(k-l)d, Xiao Yimin[1] obtained:In this paper, we obtain:
