Content: The focus is commutative algebra, i.e. commutative rings, their ideals and modules. Some topics are: spectrum of a ring, Hilbert's Nullstellensatz, primary decomposition, dimension theory, class groups, Dedekind rings.

Literature: Some standard text books on commutative algebra are the ones by Atiyah-MacDonald, Eisenbud and Matsumura. Google finds hundreds of lecture notes on this topic.

Prerequisites: The lecture is a continuation of Linear Algebra 1,2 and Introduction to Algebra (as taught by Jan Schroer). In particular good knowledge of linear algebra is required. I will also assume some very basic knowledge of ring theory as taught in Introduction to Algebra: The concepts/definitions of rings, Prime ideals, maximal ideals, localization, polynomial rings, factorial rings and some of their elementary properties. On the other hand hardly any knowledge of Galois theory and group theory is needed.

Background reading: If you did not attend the lectures by Jan Schroer and are not familiar with the topics above, chapter 2 of Langs "Algebra" or the lecture notes on ring theory by Alistair Savage cover all the necessary prerequisites on ring theory (and much more).
