metadata.name: dc.description.abstract
metadata.value: Non-isomorphic direct decompositions of torsion-free abelian groups are reflected in their
  endomorphism ring decompositions which admit matrix representations. The set of possible
  direct decompositions of a special kind matrix rings into direct sums of one-sided indecomposable
  ideals is described. This leads to the combinatorial constructions of isomorphisms
  between non-commutative differently decomposable ring structures.
