On Fundamental Algebraic Characterizations of μ -Fuzzy Normal Subgroups

Abstract

In this article, we present the study of μ -fuzzy subgroups and prove numerous fundamental algebraic attributes of this newly defined notion. We also define the concept of μ -fuzzy normal subgroup and investigate many vital algebraic characteristics of these phenomena. In addition, we characterize the quotient group induced by this particular fuzzy normal subgroup and establish a group isomorphism between the quotient groups G / κ μ and G / κ ∗ μ . Furthermore, we initiate the study of level subgroup, open level subgroup, and tangible subgroup of a μ -fuzzy subgroup and emphasize the significance of μ -fuzzy normal subgroups by establishing a relationship between these newly defined notions and μ -fuzzy normal subgroup.
