Module theory (Free and projective modules, Kaplansky theorems. Injective modules, The Baer Criterion, injetive hulls, structure of injective modules over noetherian rings, structure of divisible abelian groups, hereditary rings).

Supplementary topic: Envelopes and covers of modules. Projective and flat covers.
