On Pythagorean Fuzzy Soft Boundary

The aim of this paper is to initiate the concept of pythagorean fuzzy soft (PFS) boundary. The characterizations and properties of PFS boundary are discussed and investigated in general as well as in terms of PFS interior and PFS closure.

Keywords:

Pythagorean fuzzy soft set, pythagorean fuzzy soft topological spaces, pythagorean fuzzy soft interior(closure) pythagorean fuzzy soft boundary,
