Course Objective

The aim of this course is to study further topics in ring and module theory, including an introduction to homological algebra.

Learning Outcomes of the Course Unit

1   Will be able to understand that every module has an injective envelope and that, for left perfect rings, every left module has a projective cover.
2   Will be able to understand the method of constructing quotients for suitable rings which plays a role in the study of commutative algebra.
3   Will be able to use the basic methods for graded rings and modules.
4   Will be able to use the characterization of the rings related with the reflexivity of modules like quasi-Frobenius rings.
5   Will be able to use projective and injective resolutions of modules to obtain the left and right derived functors of the Hom functor and tensor product functor.
