✦ Synopsis

The concepts of 0-closure and d-closure operators are introduced and studied in the light of quasi-coincidence due to Pu and Liu (1980, 1980) in a fuzzy bitopological setting. As applications of these concepts, we give characterizations of fuzzy pairwise regularity and some of its weaker forms in terms of 0-closures and d-closures. The concept of fuzzy pairwise dcontinuity has been introduced and characterized by using quasi-coincidence between fuzzy sets and its relation with fuzzy pairwise almost continuity has been established in a fuzzy bitopological setting.

In this paper we introduce the concepts of 0-connectedness and 6-connectedness with the help of quasi coincidence due to Pu and Liu [6-1 for fuzzy sets in fuzzy bitopological setting as a weaker version of connectedness. In particular, we investigate their properties in almost regular, semi-regular

In this paper, we introduce subspace of a fuzzy closure space, sum of a family of pairwise disjoint fuzzy closure spaces and product of a family of fuzzy closure spaces, for the fuzzy closure spaces deÿned in Srivastava et al., 1994. We also introduce the notion of a T1-fuzzy closure space. We have

In this paper we give an approach for constructing classes of near open and near closed sets which have unusual implication relations. These new classes of subsets are based on the alternative effect of closure and interior operators with respect to two topologies. Also these classes of subsets are
