Abstract | A Pythagorean fuzzy set (PFS) is a very efficient and powerful tool for handling uncertainty and vagueness. In this paper,we present the notion of (??, ??) -Pythagorean fuzzy set (PFS) as a generalisation of Pythagorean fuzzy set (PFS). We propose anew fuzzy subgroup, called (??, ??) -Pythagorean fuzzy subgroup (PFSG). We investigate properties of our proposed fuzzysubgroup. We present the concept of (??, ??) -Pythagorean fuzzy coset (PFC) and (??, ??) -Pythagorean fuzzy normal subgroup(PFNSG). Furthermore, we define (??, ??) -Pythagorean fuzzy level subgroup (PFLSG) and establish properties of it. |
