摘要
讨论了Rd上底过程是暂留Ornstein-Uhlenbeck过程的测度值分支马尔可夫过程,考虑了其占位时过程的一个性质,证明了对任意的底空间的维数d,过程在任意一个波莱尔有界子集上花去的总占位时是有限的结论,结合超布朗运动对应的结果,发现了不同的底过程所对应的超过程的性质有时是截然不同的。
In this paper, we consider measurevalued branching Markov processes with underlying transient OrnsteinUhlenbeck processes on Rd and investigate a property of the corresponding weighted occupation time processes. We prove that for any underlying dimension d, the processes spend a finite total weighted occupation time in any bounded Borel subset of Rd. Comparing the result with that of super Brownian motion we find that the properties of superprocesses corresponding to different underlying processes are semetime quite different.
