Triangulated Matlis equivalence
TL;DR: In this article, a triangulated equivalence between the derived categories of the abelian categories of torsion modules and contramodules over a Matlis domain is presented.

The Kaplansky Test Problems - An approach via radicals
TL;DR: The existence of non-free, k-free Abelian groups and modules over some non-left perfect rings R having prescribed endomorphism algebra is established within ZFC + ◊ set theory.
Homological Theory of Representations
TL;DR: In this article, the authors introduce representation theory from its foundations up and discuss several landmark results that illustrate the power and beauty of homological methods in representation theory, including abelian and derived categories with an emphasis on localisation, spectra and purity.

On the Complexity of the Classification Problem for Torsion-Free Abelian Groups of Finite Rank
TL;DR: This paper shall discuss some recent contributions to the project of explaining why no satisfactory system of complete invariants has yet been found for the torsion-free abelian groups of finite rank n ≥ 2.
