Wθg-Closed and Wδg-Closed in [0, 1]-Topological Spaces

چکیده
In 1970, Levine 1 introduced the notion of generalized closed sets in topological spaces as a generalization of closed sets. Since then, many concepts related to generalized closed sets were defined and investigated. In 1997, Balasubramanian and Sundaram 2 introduced the concepts of generalized closed sets in fuzzy setting. Also, they studied various generalizations fuzzy continues mappings. Recently, El-Shafei and Zakari 3–5 introduced new types of generalized closed fuzzy sets in 0, 1 -topological spaces and studied many of their properties. Also, they studied various generalizations fuzzy continues mappings. In the present paper, we introduce the concepts of Wθg-closed fuzzy sets and Wδgclosed fuzzy sets and study some of their properties. Also, we introduce the concept of FT ∗ 3/4space. Moreover, we introduce and study the concepts of two new classes of fuzzy mappings, namely, fuzzy Wθg-continuous mappings and fuzzyWδg-irresolute mappings.

متن کامل$r$-fuzzy regular semi open sets in smooth topological spaces
In this paper, we introduce and study the concept of $r$-fuzzy regular semi open (closed) sets in smooth topological spaces. By using $r$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely $r$-fuzzy regular semi interior (closure) operator. Also, we introduce fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. Moreover, we investigate the ...
