On fuzzy upper and lower almost e*(resp. δS and (δp)-continuous multifunctions

Abstract

Abstract In this paper, we introduce the concepts of fuzzy upper and fuzzy lower almost e*-continuous multifunctions on fuzzy topological spaces in Ŝostak’s sense. Several characterizations and properties of these fuzzy upper (resp. fuzzy lower) almost e* -continuous multifunctions are presented and their mutual relationships are established in L-fuzzy topological spaces. Later, composition and union between these multifunctions have been studied.
