A note on additive groups of some specific associative rings

Journal Title: Annales Mathematicae Silesianae - Year 2016, Vol 30, Issue

Abstract

Almost complete description of abelian groups $(A,+,0)$ such that every associative ring $R$ with the additive group $A$ satisfies the condition: every subgroup of $A$ is an ideal of $R$, is given. Some new results for $SR$-groups in the case of associative rings are also achieved. The characterization of abelian torsion-free groups of rank one and their direct sums which are not nil-groups is complemented using only elementary methods.

We present a result on the generalized Hyers–Ulam stability of a functional equation in a single variable for functions that have values in a complete dislocated quasi-metric space. Next, we show how to apply it to prove...

Gamma graphs of some special classes of trees

A set $S \subset V$ is a dominating set of a graph $G = (V,E)$ if every vertex $v \in V$ which does not belong to $S$ has a neighbour in $S$. The domination number $\gamma (G)$ of the graph $G$ is the minimum cardinality...

We show that the solution to the orthogonal additivity problem in real inner product spaces depends continuously on the given function and provide an application of this fact.

The behaviour of weak solutions of boundary value problems for linear elliptic second order equations in unbounded cone-like domains

We investigate the behaviour of weak solutions of boundary value problems (Dirichlet, Neumann, Robin and mixed) for linear elliptic divergence second order equations in domains extending to infinity along a cone. We find...
