In this paper, we give the dual processes for superprocesses in random environments constructed by L Mytnik and the comparison theorem of these superprocesses with Dawson-Watanabe superprocesses.

From this the author deduces that an infinitely divisible probability entrance law for the superprocess is uniquely determined by an infinitely divisible probability measure on the space of the underlying entrance laws. Under an additional condition, a characterization is given for all entrance laws for the superprocess, generalizing the results of Dynkin (1989). An application to immigration processes is also discussed.展开更多
In this paper we show that tile diameter of tile support of (2, d, β)-superprocesses tends to zero a.s. at the time of extinction, and give tile probability distribution of hitting single point. For (α, d, β)-super...In this paper we show that tile diameter of tile support of (2, d, β)-superprocesses tends to zero a.s. at the time of extinction, and give tile probability distribution of hitting single point. For (α, d, β)-superprocesses, we obtain a limit theorem and some properties of the local time of it.展开更多
