An R-module A is said to be a UA-module if it is not possible to change the addition of A without changing the action of R on A. A semigroup (R, ·) is said to be a UA-ring if there exists a unique binary operation + making (R, ·, +) into a ring. In

We study abelian groups whose endomorphism rings are rings with unique addition. This means that there exists a unique binary operation of addition on the endomorphism semigroup which turns it into a ring. We also solve some close problems.

Topics relating to representation theory and near-vector spaces are explored. The general form of finite dimensional near-vector spaces of finite fields is given. We show that a near-vector...

Mixed Abelian groups with isomorphic endomorphism semigroups are studied. In particular, the question of when the isomorphism of endomorphism semigroups of Abelian groups implies the isomorphism of the groups themselves is investigated.

A semigroup (R, ·) is said to be a UA-ring if there exists a unique binary operation “+” transforming (R, ·, +) into a ring. An R-module A is said to be a UA-module if it is not possible to define a new addition in A without changing the action

An associative ring R is called a unique addition ring (UA-ring) if its multiplicative semigroup (R, · ) can be equipped with a unique binary operation+ transforming the triple (R, ·, +) to a ring. An R-module A is said to be an End-UA-module if th
