摘要: 该文证明了一般状态空间上由m-tight过程的首触时导出的容度可直接地由相应集合的首触时通过积分表示出来,利用这一结果,我们证明了函数是拟连续的几个等价命题.

关键词: 密度, 首触时, 拟连续函数

Abstract: We prove that the capacity deduced by first-touching time of m-tight process on general topological state space can be expressed throught this first touching time. With this result, we prove several equivalent statements about quasi-continuous functions.

Key words: Capacity, First tauching-time, Quasi-continuous function
