摘要
本文引入了集值映射的伪 ( * )连续性与弱 ( * )连续性概念的定义 ,研究了伪( * )连续、( * )连续及弱 ( * )连续的等价关系 .最后研究了乘积空间中的集值映射成为伪 ( * )连续和弱 ( * )
In this paper, we introduced defenitions of the Quasi- star continuity and weak - star continuity of a multifunction. Investigited the relations between mong st ar co ntinuity, quasi- star continuity and weak- star continuity. On the other hand, w e gave some results of the multifunction in product spaces.
