FUZZY p*-PRECOMPACT TOPOLOGICAL SPACES

Abstract

In this paper a new type of compactness in fuzzy topological spaces is introduced and studied by using p*-preopen sets [1] as a basic tool. We characterize this newly defined compactness by fuzzy net and prefilterbase. It is shown that this compactness implies fuzzy almost compactness [3] and the converse is true only on fuzzy p*-preregular spaces [1]. Afterwards, it is shown that this compactness remains invariant under fuzzy p*-preirresolute functions [1].
