单跳过程的弱收敛

WEAK CONVERGENCE OF SINGLE JUMP PROCESSES

假设(X^n)_(n≥1),是单跳过程序列,X是一个单跳过程。就可料特征,跳跃时和跳幅方面,本文给出了保证X^n弱收敛于X的一些充分必要条件。

Suppose (X^n)_(n≥1)and X are single jump processes, we give some necessary and sufficient conditions for the convergence in law X^n X in terms of their predictable characteristics or their jump times and size.
