摘要
证明了分支特征为,底过程为d≤3的暂留Ornstein-Uhlenbeck(O.U.)过程的超过程Xc的占位时过程关于Lebesgue测度绝对连续,且其密度过程Y(t,x)关于t≥0,x∈Rd联合连续.
In this article we proved that the occupation time process Y(t) ds of thesuper process Xt with branching mechanism and d≤3 transient Ornstein-Uhlen-beck (O. U.) underlying process,is absolutly continuous with respect to the Lebesgue mea-sure, and its density process Y(t,x) is joint continuous in t ≥ 0,x∈e Rd.
