Abstract

Let X=(Xt,t0)X=(X_t, t\geq 0) be a superprocess in a random environment described by a Gaussian noise W={W(t,x),t0,xRd}W=\{W(t,x), t\geq 0, x\in \mathbb{R}^d\} white in time and colored in space with correlation kernel g(x,y)g(x,y). When d3d\geq 3, under the condition that the correlation function g(x,y)g(x,y) is bounded above by some appropriate function gˉ(xy)\bar{g}(x-y), we present the quenched and annealed Strong Law of Large Numbers and the Central Limit Theorems regarding the weighted occupation measure 0tXsds\int_0^t X_s ds as tt\to \infty.
