Pythagorean Fuzzy Open Maps and Homeomorphisms Pythagorean Fuzzy e-open sets in topological spaces

Abstract

In this paper, we present the notions of Pythagorean fuzzy e-open and e-closed mappings within
the framework of Pythagorean fuzzy topological spaces and explore several of their fundamental
properties. The concepts of e-open and e-closed maps are formally defined and supported with
illustrative examples. Furthermore, the study is extended to cover Pythagorean e-homeomorphism,
Pythagorean e-completely homeomorphism, and Pythagorean eT 1 -spaces, where a number of re-
