| 摘 要： | 本文在一般拓扑空间（Ｘ，Ｔ）与模糊拓扑空间（Ｙ，Ｔ１）之间引入模糊下与上半预连续多值映射的概念，并借助于映射Ｆ，与Ｆ＾８研究了它们的一些基本性质，同时讨论了它们和已有的模糊多值映射的关系。

| Abstract: | Between a general topological space (X. T) and a fuzzy topological space (Y.T, ) .the concepts of fuzzy lower and upper semi precontinuous and semi-precontinuoual multifunctional propertics a re introd Liced. and their various properties are investigated. By using the mapping F.and F, several propertics of a fuzzy lower and upper semi-precontinuous multifunctions are studied. |
