On various weak fuzzy pairwise retracts

摘要

The notion of a fuzzy retract was introduced by Rodabaugh [J. Math. Anal. Appl. 79 (1981) 273] and this notion was extended to the fuzzy bitopological setting [J. Fuzzy Math. 9(1) (2001) 207]. In this paper, we define the notions of fuzzy pairwise semiretracts, fuzzy pairwise preretracts, fuzzy pairwise strongly semiretracts, fuzzy pairwise less strongly semiretracts and fuzzy pairwise semi-preretracts. We establish some properties of these concepts. Moreover the relations between these new concepts are discussed.
