| 摘 要： | 在模糊半预开集的基础上,引入了模糊下与上几乎半预连续多值映射的概念,借助于映射F*与F*研究了它们的性质及其等价刻画.结果表明,所引入的几乎半预连续模糊多值映射具有一系列好的性质,从而丰富了已有的结果.

| Abstract: | Based on the definition of fuzzy semi-preopen sets, the concepts of fuzzy lower and upper almost semi-precontinuous mulitifunctions as well as fuzzy almost semi-precontinuous mulitifunctions are introduced.By using of the mapping F* and F*,some of their basic properties and equivalent characterizations are studied.It is shown that the fuzzy almost semi-precontinuous mulitifunctions have a series of good properties.Therefore,the existing results are enriched. |
