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 …

This chapter examines semigroups and monoids, studies their basic properties, and
presents several examples. The first section defines binary operations and presents several …

An abelian group A is called self-small if direct sums of copies of A commute with the
covariant Hom (A,-) functor. The paper presents an elementary example of a non-self-small …

We develop algorithms for determining properties of finite abelian groups related to the
notions of extending and lifting groups. Thus, we give efficient methods, on one hand to …

We identify some classes C of mixed groups such that if G∈ C has the cancellation property
then the Walk-endomorphism ring of G has the unit lifting property. In particular, if G is a self …
