Matrix rings are prominent in abstract algebra. In this paper we give an overview of the theory of matrix near-rings. A near-ring differs from a ring in that it does not need to be abelian and one of the distributive ...
Nowadays some promising authenticated group key agreement protocols are constructed on braid groups, dynamic groups, pairings and bilinear pairings. Hence the non-abelian structure has attracted cryptographers to cons...
Let N be a prime near-ring. We show two main results on the commutativity of N: (1) If there exist k, l ∈ N such that N admits a generalized derivation D satisfying either D([x,y]) = xk[x,y]xl for all x,y ∈ N o...
In this paper we first prove that a near-ring admits a derivation if and only if it is zero-symmetric. Also, we prove some commutativity theorems for a non-necessarily 3-prime near-ring R with a suitably-constrained d...
In 1999, Kim and Kwak asked one question that "Is a ring R 2-primal if Op C P for each P ∈ mSpec(R)?'. In this paper, we prove that if Op has the IFP for each P ∈ mSpec(N), then OR C P for each P ∈ mSpec(N...

The concept of(∈,∈∨q)-fuzzy subnear-rings(ideals) of a near-ring is introduced and some of its related properties are investigated.In particular,the relationships among ordinary fuzzy subnear-rings(ideals),(...
The near-rings in this letter always stand for zero-symmetric left nor-rings. An additive endomorphism D of a near-ring N is called a derivation on N if D(xy) =xD(y) +D(x)y for all x, y ∈ N. A near-ring N is said to ...
