Basic algebraic or homological invariants of commutative rings are introduced. Methods for their analysis and their behaviour under classical ring constructions are investigated. Central results of the theory of commutative rings are presented.

Qualification Goals

Students can

  • understand and explain basic properties of commutative rings,
  • use algebraic or homological methods for the analysis of commutative rings,
  • understand and apply construction methods of commutative rings.

They deepen

  • the practice of mathematical working methods (development of mathematical intuition and its formal justification, training of the ability to abstract, proof methods),
  • in the recitation class, their oral communication skills through discussion and free speech in front of an audience.


None. The competences taught in the following modules are recommended: either Foundations of Mathematics and Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis, either Algebra [Bachelor Module] or Algebra [Lehramt Module].

This page describes a module according to the latest valid module guide in Sommersemester 2021. Most rules valid for a module are not covered by the examination regulations and can therefore be updated on a semesterly basis. The following versions are available in the online module guide:
