弱α—连续集值映射

The weak α-continuous set value mappings

本文给出了弱α——连续集值映射的概念.将关于弱α——连续函数的一些结果推广到集值映射.改进了文[3]中的两个重要定理.

In this paper, a concept of weak a-continuous set value mappings is given. And some conclusions for weak a-continuous functions are generalized to the set value mappings. Two important theorems in [3] are improved.
