Specialized topological methods are presented which contribute to the investigation of topological spaces, whcih are motivated by questions in algebra, algebraic geometry or combinatorics. These can be, for example, methods of homotopy theory or the theory of manifolds.

Qualification Goals

The students

  • know specialized topological constructions (e.g. from homotopy theory) and their algebraic invariants,
  • can use algebraic invariants of topological spaces in other areas (e.g. algebra, combinatorics),
  • can profitably apply methods from other areas (e.g. algebra, combinatorics) to topological questions.

They deepen

  • the practice of mathematical methods (development of mathematical intuition and its formal justification, training of the ability to abstract, proof methods),
  • in the recitation classes, 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, Algebra. In addition, the competences are recommended which are taught in an introductory course on topology.

This page describes a module according to the latest valid module guide in Winter semester 2020/21. 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:

The module guide contains all modules, independent of the current event offer. Please compare the current course catalogue in Marvin.
