MORE ON OPEN SETS IN FERMATEAN FUZZY TOPOLOGICAL SPACES AND ITS APPLICATION

The purpose of this paper is to introduce the concept of 𝕱𝓕𝛿os (resp. 𝕱𝓕𝛿𝒫os, 𝕱𝓕𝛿𝒮os, 𝕱𝓕𝛿𝛼os and 𝕱𝓕𝛿𝛽os) in Fermatean fuzzy topological spaces. We focus on the fundamental operations and examples for the 𝕱𝓕𝛿os (resp. 𝕱𝓕𝛿𝒫os, 𝕱𝓕𝛿𝒮os, 𝕱𝓕𝛿𝛼os and 𝕱𝓕𝛿𝛽os) of Fermatean fuzzy topological spaces. Also we give an real life application for decision making using entropy measure on Fermatean fuzzy sets.
