Weak Structures on Pythagorean Fuzzy Soft Topological Spaces

Abstract

In this paper, we initiate the topological structures of pythagorean fuzzy soft semi-open sets and pythagorean fuzzy soft semi-closed sets. Furthermore, the concept of pythagorean fuzzy soft semi-interior, pythagorean fuzzy soft semi-closure are presented. Also some related properties are investigated.

Keywords

• Pythagorean fuzzy soft set
• pythagorean fuzzy soft topological spaces
• pythagorean fuzzy soft semi-open(closed) sets
• pythagorean fuzzy soft semi-interior
• pythagorean fuzzy soft semi-closure
