Abstract

Using the idea of the new sort of fuzzy subnear-ring of a near-ring, fuzzy subgroups, and their generalizations defined by various researchers, we try to introduce the notion of (ϵ,ϵ∨q)-fuzzy ideals of N-groups. These fuzzy ideals are characterized by their level ideals, and some other related properties are investigated.

Highlights

  • Introduction and Basic DefinitionsThe concept of a fuzzy set was introduced by Zadeh [1] in 1965, utilizing what Rosenfeld [2] defined as fuzzy subgroups

  • We extend the idea of (ε, ε ∨ q)-fuzzy ideals of nearrings to the case of N-groups and introduce the idea of fuzzy cosets with some results

  • We prove the result for (ε, ε ∨ q)-fuzzy ideal S

Summary

Introduction

Introduction and Basic DefinitionsThe concept of a fuzzy set was introduced by Zadeh [1] in 1965, utilizing what Rosenfeld [2] defined as fuzzy subgroups. A fuzzy subset A of a group G is called a fuzzy subgroup of G if it satisfies the following conditions: (i) A(x + y) ≥ min{A(x), A(y)}, (ii) A(−x) ≥ A(x), for all x, y ∈ G.
