W[theta]g -Closed and W[delta]g -Closed in [0,1] -Topological Spaces

We investigate various classes of generalized closed fuzzy sets in [0,1] -topological spaces, namely, Wθg -closed fuzzy sets and Wδg -closed fuzzy sets. Also, we introduce a new separation axiom F[superscript]T3/4[low *][/superscript] of the [0,1] -topological spaces, and we prove that every F[super...

Also, we introduce a new separation axiom F[superscript]T3/4[low *][/superscript] of the [0,1] -topological spaces, and we prove that every F[superscript]T3/4[low *][/superscript] -space is a F[subscript]T3/4[/subscript] -space. Furthermore, we using the new generalized closed fuzzy sets to construct new types of fuzzy mappings.
