IMPORTANT:

Attendance of lectures is required.!

Course Code: 2360771

Schedule:
Mondays:       10:40-12:30  at room M-215
Wednesdays:   09:40-10:30
at room M-215

Content: Categories, functors, derived functors, extensions, resolutions, homology and cohomology of
complexes. Some applications depending on the consent of the instructor such as modular
representation theory or cohomology of groups or Lie algebras, algebraic topology.

Course Objectives:
1-
To introduce standart concepts of homological algebra such as Ext and Tor and apply these in the setting of specific areas chosen
depending the consent of the instructor.
2-
To prepare students to a current research area, introduce them open questions.
3-
To enable students with the computational skills such as computation of homology groups, cohomology groups which are needed in
algebraic topology, algebraic geometry, etc...

Course Learning Outcomes:
Obtain knowledge of the facts and techniques from homological algebra e.g. diagram chasing etc.
Apply homological algebra methods to problems in algebra and topology.
Compute homology and cohomology groups of spaces and groups
