Course Objective

This course will cover the theory of special classes of modules and the theory of homological dimensions of modules and rings.

Learning Outcomes of the Course Unit

2   Will be able to use Schanuel s lemma when computing projective and injective dimensions of modules.
3   Will be able to understand the homological classification of rings by their global dimension.
4   Will be able to use the uniform dimension of modules.
5   Will be able to understand the notions of essentiality, singularity and denseness of submodules.
