A Novel Approximation of Pythagorean Fuzzy Sets via Proximal Relator Spaces
Özlem Tekin
Pythagorean fuzzy sets are an advanced tool of two-dimensional membership functions that are characterized by a membership degree and a non-membership degree satisfying the condition that the square sum of its membership degree and non- membership degree is equal to or less than one In this paper, it is studied a new approach via proximal spaces for Pythagorean fuzzy sets. To do this, the Pythagorean fuzzy proximity axioms are defined on proximal relator spaces.
