Kuroki (Kuroki, ) initiated the notion fuzzy ideals, bi-ideals, quasi-ideals of semigroups. The book by Mordeson (Mordeson, Malik & Kuroki, ), deals with the theory of fuzzy semigroups and their use in fuzzy coding, fuzzy finite state machines and fuzzy languages. Ideals theory in semigroups, like all other algebraic structures, play an important role in studying them. Steinfeld gave the idea of quasi ideals in rings and semigroups respectively in his articles [12] and [11]. Iseki [5] developed this concept for semirings having no zero and studied important characterizations of semirings using quasi ideals.

Math. 9, 55–61, In Dixit and Dewan studied about the quasi-ideals in ternary semigroups. are generalization of right ideals, lateral ideals and left ideals. In S.

The characterization of regular rings, semigroups or ordered semigroups in terms of right ideals and left ideals is well known,,. The characterization of regular le-semigroups in terms of right ideal elements and left ideal elements is known as well. In this paragraph we give the analogous result by means of fuzzy sets. of bi-ideals in rings and semigroups were introduced by Lajos and Szasz [11]. In , Steinfeld [47] rst introduced the notion of quasi ideals for semigroups and then for rings. Iseki [4, 5, 6] introduced the concept of quasi ideal for a semiring. Henriksen [3] studied ideals in semirings. Quasi ideals in semirings studied by Jagtap and Pawar.

In this paper, we study the concept of minimal quasi-ideals in ternary semiring and prove some standard results analogous to ring theory. We also introduced the concept of a \(Q\)-simple ternary semiring and \(0\)-\(Q\)-simple ternary semiring and characterize \(0\)-minimal quasi-ideals in terms of \(Q\)-simple ternary semiring.

Springer Reference Works are not included. This book, along with volume I, which appeared previously, presents a survey of the structure and representation theory of semi groups. Volume II goes more deeply than was possible in volume I into the theories of minimal ideals in a semi group, inverse semi groups, simple semi groups, congruences on a semi group, and the embedding of a semi group in a by: Steinfeld surveyed widely the generalization for the notion of quasi-ideal in rings and semigroups in Dixit and Dewan studied about the quasi-ideals and bi-ideals of ternary semigroups.

Abstract Several statements on quasi-ideals of semirings are given in this paper, where these semirings may have an absorbing element O or not.

In Section 2 we characterize regular semirings and regular elements of semi-rings using quasi-ideals (cf. Thms.and ). In Section 3 we deal with (O −) minimal and canonical quasi-ideals. The aim of this note is to use some structural properties of quasi-commutative semigroups to get information on their ideals.

Many classical notions of semigroups were extended to Γ-semigroups. In this paper, we study some properties of minimal quasi-ideals in Γ. Quasi-ideal was first introduced by O. Steinfeld for semigroups and then for rings by the same author O. Steinfeld where it is seen that quasi-ideal is a generalization of left and right ideals.
