On Zero-Symmetric Left Centrally Prime Near-Rings [PDF]

Kirkuk University Journal-Scientific Studies, 2007
Our aim in this paper is: to give some properties of zero-symmetric left centrally prime near-rings, then looking for those conditions which make zero-symmetric left centrally prime near-rings abelian, so that several conditions are given under which zero-symmetric left centrally prime near-rings become abelian.

Partitioned groups and the additive structure of centralizer near-rings [PDF]

Proceedings of the Edinburgh Mathematical Society, 1984
If G is a finite group and A is a group of automorphisms of G, the “centralizer” nearring C(A, G) consists of the identity-preserving maps from G to itself which commute with the action of A. The main concern of this paper will be with the additive structur of C(A, G) in the case that this near-ring is semisimple.

The lattice of left ideals in a centralizer near-ring is distributive [PDF]

Proceedings of the American Mathematical Society, 1982
A decomposition theorem for a left ideal in a finite centralizer near-ring is established. This result is used to show that the lattice of left ideals in a finite centralizer near-ring is distributive.

Matrix Near-rings over Centralizer Near-rings

Algebra Colloquium, 2000
In 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.

Centralizer Near-rings, Matrix Near-rings and Cyclic p-Groups

Algebra Colloquium, 2005
If 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 ...

Distributor and j2-radical ideals of generalized centralizer near-rings

Communications in Algebra, 1997
In 1980, Maxson and Smith [1] determined the J2-radical ideal for the ceiitralizer near-ring MA(G), where A is a group of automorphisms over a group G. Further, in 1985, Smith [4] generalized MA(G) to the class of generalized ceiitralizer near-rings. In this paper we determine both the J2-radical and the distributor ideals for the class of generalized ...
