On Modules of Homogeneous Mappings and let . be the ring of all R-endomorphisms of .. Of course .(.) is contained in .(.) and, as many examples show, (, [.], , ), in general .(.) is larger then .(.)..In this paper we try “to measure a distance” between .(.) and .(.) under some additional assumptions on . and G.

When is a centralizer near-ring isomorphic to a matrix near-ring? Part 2ubnear-ring of the centralizer near-ring ..(..). We find conditions such that .(..(.);.) is a proper subset of ..(..). Assuming both . and . are abelian we find conditions under which .(..(.);.) equals ..(..).

Some Results on Derivations in NearringsLet . denote a 3-prime near-ring. We prove that if 2. ≠ {0} and .. and .. are nonzero derivations on ., then .... cannot act as a derivation on a nonzero additively-closed semigroup ideal. We then establish some results involving conditions of form .(.).(.) = 0, where . is a derivation on . and . is an endomorphism of ..

A Note on Pseudo-Distributivity in Group Near-RingsIt is shown that the group near-ring constructed from a pseudo-distributive near-ring and an arbitrary group is a ring.
