关于集值上鞅分解式的注记

Remark on decomposition of the set-valued supermartingle

讨论了集值上鞅与支撑函数的一些性质,利用支撑函数研究了一般Banach空间上集值上鞅的Riesz分解定理,推广和改进了以往的结果。

The properties of set -valued supermartingale and suport function are discussed,using suport function ,we get Riesz decomposition theorem of set-valued supermartingale in general Banach space, these results extend and improve the earler results.
