Quotient structure of interior-closure texture spaces

Quotient Structure of Interior-closure Texture Spaces

In this paper, we consider quotient structure and quotient difunctions in the context of interior and closure operators on textures in the sense of Dikranjan-Giuli. The generalizations of several results concerning separation and quotient mapping are presented. It is shown that the category of interior-closure spaces and bicontinuous difunctions has a T0 reflection. Finally, we introduce some c...

Delta Closure and Delta Interior in Intuitionistic Fuzzy Topological Spaces

Due to importance of the concepts of θ-closure and δ-closure, it is natural to try for their extensions to fuzzy topological spaces. So, Ganguly and Saha introduced and investigated the concept of fuzzy δ-closure by using the concept of quasicoincidence in fuzzy topological spaces. In this paper, we will introduce the concept of δ-closure in intuitionistic fuzzy topological spaces, which is a g...

rgα-Interior and rgα-Closure in Topological Spaces

In this paper, we introduce rgα-interior, rgα-closure and some of its basic properties. We define τrgα and prove that it forms a topology on X. Mathematics Subject Classification: 54C10, 54C08, 54C05
