摘 要: 本文在[1]的基础上,针对非常值分枝率对应的一类广泛超α-稳定过程占位时过程,证明了在非临界情况下其渐近行为与[1]中相同,但在临界时其渐近性依赖于分枝率在无穷远点的极限行为,从而得到了更为精细的结果. Motivated by Fleischmann and Gaitner(1986),we shall investigate in this paperthe asymptotic behaviors of occupation time processes for a class of super-α-stable processeswith non-constant branching rates.We obtain the same results as [1] in the supercriticaland subcritical cases.However,we find that the asymptotic behaviors depend on the limitof branching rates at infinity in the critical case,and thereby obtain a refined result.
