集值Pramart的一类鞅逼近

Another class martingale approximation of set-valued Pramart

在X*可分的条件下,首先讨论了集值Pramart有关支撑函数和距离函数的性质,利用支撑函数和距离函数研究了集值Pramart鞅逼近,在此基础上,给出了集值Pramart的一类鞅分解.

In this paper,The properties of set-valued pramart with suport function and distance function are discussed,using suport function and distance function,we get martingale approximation of set-valued Pra-mart,including its martingale decomposition.
