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.

On derivations in near-rings and rings
Mathematical Journal of Okayama University, 1992In a near-ring \(R\) a derivation \(D\) is called an scp-derivation if \([x,y] = [D(x), D(y)]\), a Daif 1(2)-derivation if \(D(xy) - D(yx) = [x, y] (=[-x, y])\) (\(\forall x, y \in R\)). Various commutativity (and distributivity) results linked to such derivations are given: e.g.

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 ...

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]

Planar Near-Rings, Sandwich Near-Rings and Near-Rings with Right Identity
2005We show that every near-ring containing a multiplicative right identity can be described as a centralizer near-ring with sandwich multiplication. Using this result we characterize planar near-rings and near-rings solving the equation xa=c in terms of such centralizer near-rings with sandwich multiplication.

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.

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].

The principal theorem states that a finite non-constant near-ring N is geometric if and only if it is strongly monogenic. This provides the basis for a well-defined representation of the group space on the group \(\{Z\to aZ+b| \quad a,b\in N,\quad a\neq 0\}\) acting on the underlying set of N.
