Some Structures on Pythagorean Fuzzy Topological Spaces

Abstract

In this paper, we introduced some operations such as Pythagorean fuzzy interior, Pythagorean fuzzy closure, Pythagorean fuzzy boundary, Pythagorean fuzzy basic on Pythagorean fuzzy topological spaces. Also, the notions of Pythagorean fuzzy open (closed) functions and Pythagorean fuzzy homeomorphism are introduced, and their basic properties are investigated. , , , , , .
