چکیده
In this paper we discuss the concepts of rough quasi-ideals and rough bi-ideals in a Γ-semigroup. We study some properties of the lower and upper approximations of such ideals with respect to a congruence relation in Γ-semigroup . Mathematics Subject Classification: 03Exx, 28E15

ON ROUGH (m,n) BI-Γ-HYPERIDEALS IN Γ-SEMIHYPERGROUPS
The notion of (m,n)-ideals of semigroups was introduced by Lajos [13, 14]. Later (m,n) quasi-ideals and (m,n) bi-ideals and generalized (m,n) bi-ideals were studied in various algebraic structures. The notion of a rough set was originally proposed by Pawlak [16] as a formal tool for modeling and processing incomplete information in information systems. Some authors have studied the algebraic pr...
متن کاملCharacterizing Ordered Bi-Ideals in Ordered Γ-Semigroups
The notion of a &Gamma-semigroup was introduced by Sen [8] in 1981. We can see that any semigroup can be considered as a &Gamma-semigroup. The aim of this article is to study the concept of (0-)minimal and max- imal ordered bi-ideals in ordered &Gamma-semigroups, and give some charac- terizations of (0-)minimal and maximal ordered bi-ideals in ordered &Gamma- semigroups analogous to the charact...
متن کاملIntuitionistic Q-Fuzzy Prime Bi-∧-Ideals of ∧-Semigroups
After the introduction of fuzzy sets by Zadeh [20] in 1965, several researchers have been working on the generalization of the fuzzification. In 1986, Atanassov [2] introduced the notion of intuitionistic fuzzy sets. For more details on the intuitionistic fuzzy sets, we refer to [2-4]. Fuzzy sets are intuitionistic fuzzy sets but the converse is not necessarily true [18]. Kim and Jun [7, 8] int...
متن کاملOn Q-Fuzzy Ideals in Γ-Semigroups
In this paper the concept of Q-fuzzification of ideals of Γ-semigroups has been introduced and some important properties have been investigated. A characterization of regular Γ-semigroup in terms of Q-fuzzy ideals has been obtained. Operator semigroups of a Γ-semigroup has been made to work by obtaining various relationships between Q-fuzzy ideals of a Γ-semigroup and that of its operator semig...
متن کاملOn Cartesian Product of Fuzzy Completely Prime and Fuzzy Completely Semiprime Ideals of Γ-Semigroups
The purpose of this paper is to study some properties of cartesian product of fuzzy completely prime ideals and fuzzy completely semiprime ideals of Γ-semigroups. Operator semigroups of a Γ-semigroup has been made to work by obtaining various relationships between cartesian product of fuzzy ideals (fuzzy completely prime ideals, fuzzy completely semiprime ideals) of a Γ-semigroup and that of it...
