This paper is devoted to study some relationships of trusses with rings. We characterize abelian groups A such that every truss with retract A has exactly two non-commutative multiplications. We describe commutative rings with nontrivial multiplicati

An abelian group [Formula: see text] is called a [Formula: see text]-group if every associative ring with the additive group [Formula: see text] is filial. The filiality of a ring [Formula: see text] means that the ring [Formula: see text] is associa

It is shown that there is a close relationship between ideal extensions of rings and trusses, that is, sets with a semigroup operation distributing over a ternary abelian heap operation. Specifically, a truss can be associated to every element of an

The paper deals with new specific constructions of indecomposable torsion-free abelian groups of rank two and nonzero rings on them. They illustrate purely theoretical results and complement quite rare examples obtained during the classical as well a

This note contains an example of two non-isomorphic algebras A and B over an arbitrary field K such that the algebras $\widetilde {A}$ A ~ and $\widetilde {B}$ B ~ obtained form A and B, respectively, by the standard process of adjoining an identity,

The main aim of this note is to give a new and elementary proof of the Beidar theorem, which asserts that for every positive integer n there exists a homomorphically closed class of rings with the ...

The relation between the structure of a ring and the structure of its additive group is studied in the context of some recent results in additive groups of mixed rings. Namely, the notion of the square subgroup of an abelian group, which is a general
