Matrix Near-rings over Centralizer Near-rings
Algebra Colloquium, 2000In the most widely accepted definition of matrix near-rings [\textit{J. D. P. Meldrum} and \textit{A. P. J. van der Walt}, Arch. Math. 47, 312-319 (1986; Zbl 0611.16025)], there are two obvious ways of linking ideals in the base near-ring to ideals in the matrix near-ring.

In this paper we introduce the concept of Boolean near-rings. Using any Boolean ring with identity, we construct a class of Boolean near-rings, called special, and determine left ideals, ideals, factor near-rings which are Boolean rings, isomorphism classes, and ideals which are near-ring direct summands for these special Boolean near-rings.Blackett [6]

Until this article, there has not been an acceptable approach to the concept of a near-ring of matrices over an arbitrary near-ring. The authors overcome the inherent problems associated with arrays and are motivated by the fact that for a ring, each matrix represents an endomorphism of \((R^ n,+)\) and as such it is derived from the endomorphisms of ...

Special radicals of near-rings and Γ-near-rings
Periodica Mathematica Hungarica, 1994All near-rings are 0-symmetric and right distributive. A \(\Gamma\)-near- ring \((M, +, \Gamma)\) is a set \(M\) and a set of binary operators \(\Gamma\) on \(M\) such that \((M, +, \gamma)\) is a near-ring for each \(\gamma \in \Gamma\), and a generalized associative law holds.

Let \(R\) be a left near-ring and let \(E(R^+)\) be the monoid of endomorphisms of \((R,+)\). For each \(a\in R\), let \(a_\ell\colon R\to R\) be the left-multiplication map \(x\mapsto ax\) and note that \(a_\ell\in E(R^+)\). Let \(L\colon R\to E(R^+)\) be defined by \(L(a)=a_\ell\), and call \(R\) an \(E\)-near-ring if \(L\) is a bijection.

Blackett [4] introduced the concepts of near-ring homomorphism and near-ring ideal. Beidleman [1] established the fundamental homomorphism theorem and the isomorphism theorems for (left) near - rings obeying the condition that 0.a = 0 for every a in the near-ring. Several others, for example [3], [5], and [7], have taken up the study of ideals.

In this paper, we consider the problem of how to define [Formula: see text]-nearness ring in the sense of Nobusawa theory which extends the notion of a nearness ring and [Formula: see text]-rings [N. Nobusawa, Osaka J. Math. 1 (1964) 81–89; M. A. Öztürk and E. İnan, Annals of Fuzzy Mathematics and Informatics 17(2) (2019) 115–131].

NEW KINDS OF NEAR-RINGS FROM OLD NEAR RINGS
JP Journal of Algebra, Number Theory and Applications, 2018Summary: In this paper, we construct that a new kind of near-ring, that is, \((e, t)\)-near-ring \((R, +,\ast)\) with given addition in \(R\) and new multiplication \(\ast\) which is expressed in terms of the original multiplication and addition by defining \(a\ast b\) to be a polynomial in \(a\) and \(b\), from a given near-ring \((R, +, \cdot ...

Centralizer Near-rings, Matrix Near-rings and Cyclic p-Groups
Algebra Colloquium, 2005If G is a finite group and [Formula: see text] is a group of automorphisms of G, then it is known that the matrix near-ring [Formula: see text] is a subnear-ring of the centralizer near-ring [Formula: see text] for every m ≥ 2. Conditions are known under which [Formula: see text] is a proper subnear-ring of [Formula: see text], and if [Formula: see ...

Summary: In this paper, the authors have defined the valuation near ring. They have proved some theorem, for example, they have shown every valuation near ring is a local near ring and the ideals of \(N\) are totally ordered by inclusion. Also, the symbol valuation \(N\)-group in near rings has been introduced. Finally, every valuation \(N\)-group is a
