Weak Structures on Pythagorean Fuzzy Soft Topological Spaces

Weak Structures on Pythagorean Fuzzy Soft Topological Spaces

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.
