Abstract

We introduce the notion of (i-v) semiprime (irreducible) fuzzy ideals of semigroups and investigate its different algebraic properties. We study the interrelation among (i-v) prime fuzzy ideals, (i-v) semiprime fuzzy ideals, and (i-v) irreducible fuzzy ideals and characterize regular semigroups by using these (i-v) fuzzy ideals.

Highlights

  • Zadeh [1] first introduced the concept of fuzzy sets in 1965

  • An idea of connecting the fuzzy sets and algebraic structures came first in Rosenfeld’s mind. He first introduced the notion of fuzzy subgroup [2] in 1971 and studied many results related to groups

  • After that fuzzification of any algebraic structures has become a new area of research for the researchers

Summary

Introduction

Zadeh [1] first introduced the concept of fuzzy sets in 1965. After that it has become an important research tool in mathematics as well as in other fields. Let I be a semiprime ideal of a semigroup S and μan (i-v) fuzzy subset of S defined by μ (p) = {1[̃α, , β] , when p ∈ I; otherwise, (2) A nonconstant (i-v) fuzzy ideal μof a semigroup S is called an (i-v) completely semiprime fuzzy ideal of S if for any (i-v) fuzzy point xã of S xã ∘ xã ∈ μimplies xã ∈ μ. Let χI be an (i-v) completely semiprime fuzzy ideal of S.
