Some properties of f max. o. s. and f. min. o. s. in fuzzy topological spaces defined on a fuzzy set

Abstract

In this work we introduce (Fuzzy Maximal Open Set) and (Fuzzy Minimal Open Set). We introduce these fuzzy set in a fuzzy topological spaces defined on a fuzzy set Iƒ instead of crisp set . We studied some properties of these fuzzy sets and some interrelationships between them.
