Some Aspects of Pairwise Fuzzy Preopen Sets inFuzzy Bi-topological Spaces

摘要

In this paper, considering a bitopological space, the concepts of pairwise fuzzypreopen sets, pairwise fuzzy pre- T_1space, pairwise fuzzy pre- T_2space and pairwise fuzzy pre-continuity are introduced. Using different conditions on two fuzzy topologiesand their mixed fuzzy topology, some results are established on pairwise separationaxioms and continuity.
