Course Objective

The aim of this course is to introduce the basic methods in homological algebra.

Learning Outcomes of the Course Unit

1	Will be able to use the properties of the adjoint functors Hom and tensor product in the categories of modules.
2	Will be able to find Ext(C,A) using projective or injective resolutions.
3	Will be able to find Tor(A,B) using projective or injective or flat resolutions.
4	Will be able to use the properties of the rings characterized by their homological dimensions.
5	Will be able to understand how the homological methods for modules are generalized to homology in abelian categories.
