Description:
A ring R is called left comorphic if for every a ∈ R there exists b ∈ R such that the left and right annihilators satisfy Ra = l(b) and r(a) = bR. In this paper, the Abelian groups with left comorphic

Description:
If H is a subgroup of an Abelian p-group G, we say G is H-fully transitive if using the height valuation from G, for every x ∈ H, every valuated (i.e., non-height decreasing) homomorphism x → G extend

Description:
We define an object (group, ring, module, algebra, etc.) to be Bassian if it is not possible to embed it in a proper homomorphic image of itself. Here we study this concept for Abelian groups and achi

Description:
We describe fully quasitransitive torsion-free groups in the class of groups whose endomorphism ring is a skew field as well as in the class of groups that are direct sums of homogeneous groups. We pr
