In this paper, we have used the fuzzy topologies tau(1) and tau(2) to
generate a family tau(s), which is a supra fuzzy topology on X. Using
the family tau s, we introduce and study the concepts of separation ax
ioms, continuity (resp. openness, closedness) of a mapping and compact
ness for a fuzzy bitopological space (X, tau(1), tau(2)). Our definiti
ons preserve much of the correspondence between concepts of fuzzy bito
pological spaces and the associated fuzzy topological spaces. We then
investigate the relationship between these concepts and their correspo
ndence with the fuzzy bitopological spaces (Kandil and El-Shafee, 1991
).
