| 摘 要： | 定义了广义开集和强广义开集.得出了有限个强广义开集之并仍是强广义开集,强广义开集一定是广义开集,强广义开集的内部是强广义开集.利用强广义开集引入强广义上(下)弱半连续多值映射等概念,讨论了其等价条件,并研究了它们的各种性质.

| Abstract: | The generalized open sets and strongly generalized open sets are defined.The authors obtain that the union of finite strongly generalized open sets remains strongly generalized open set,the strongly generalized open set is generalized open set,and the interior of strongly generalized open set is strongly generalized open set.The concepts of strongly generalized lower and upper weakly semicontinuous multifuntions with strongly generalized open sets are introduced,their equivalent conditions are discussed and their various properties are investigated. |
