Lecture Course on Algebra (Master)
Birgit Richter, email: birgit.richter at uni-hamburg.de
Plan: The aim of this course is to present the basics of homological algebra. Methods from homological algebra are used in many areas of pure mathematics. I will develop the theoretical background (rings and modules, basics from category theory) and then discuss resolutions and derived functors. Our two main applications are Hochschild homology (which is a homology theory for associative algebras) and group homology. Homological algebra is pretty useless unless you are able to calculate things, so I'll also discuss spectral sequences.
If you plan to do a master thesis on a topic related to this lecture course, then please contact me as early as possible.
