Almost continuous and weakly continuous fuzzy set valued functions on bitopological spaces
The aim of this paper is to introduce and study almost continuous and weakly continuous fuzzy pairwise multifunctions, where the domain of these functions is a bitopological space with their values as arbitrary fuzzy sets in a fuzzy bitopological space. Several characterizations and properties of these multifunctions along with their mutual relationships are established. (C) 2000 Elsevier Science B.V. All rights reserved.
