本文建立了临界超过程X= X_t,tge 0的条件极限定理.首先,我们确定不灭绝的比率。然后,我们表明,对于一个大类的功能$f$,在时间$t$不灭绝的条件下,极限,作为$t\to\infty$,$t^{-1}\langle f,X_t\rangle$存在于分布,我们确定这个极限。最后,在一定的条件下,我们还建立了t时刻不灭条件下$\langle f,X_t\rangle$的中心极限定理.
In this paper we establish some conditional limit theorems for some critical superprocesses $X=\{X_t, t\ge 0\}$. First we identify the rate of non-extinction. Then we show that, for a large class of functions $f$, conditioned on non-extinction at time $t$, the limit, as $t\to\infty$, of $t^{-1}\langle f, X_t\rangle$ exists in distribution and we identify this limit. Finally, we also establish, under some conditions, a central limit theorem for $\langle f, X_t\rangle$ conditioned on non-extinction at time $t$.
