✦ Synopsis

Given a fuzzy bitopological space (X, Tl,172), we introduce a new notion of fuzzy pairwise separation axioms by using the family of its level bitopologies t~(zl), i~(z2), ctE[0,1). We prove that these concepts are good extension and we compare them with its corresponding FPTi (Kandil and EI-Shafee, 1991 ) and FPT~' ) (i ---0, l, 2, 3, 4), respectively. We show that these notions are not equivalent and we give a number of examples which illustrate this fact.
