Possible topics include:

  • ordinary cohomology theories and Poincaré duality.
  • homotopy groups
  • Fibers and cofibrations
  • Eilenberg-MacLane spaces
  • spectral sequences
  • Equivariant cohomology
  • Characteristic classes

Qualification Goals

The students

  • know common and also advanced topological constructions,
  • master the interplay between algebra and topology,
  • understand connections between different subfields of algebraic topology (e.g., homology, cohomology, homotopy) and also adjacent fields,
  • can recognize and use functorial relations.
  • have deepened mathematical working methods (development of mathematical intuition and its formal justification, abstraction, proof),
  • have improved their oral communication skills in exercises 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, Algebraic Topology I.


The module can be attended at FB12 in study program(s)

  • B.Sc. Mathematics
  • M.Sc. Mathematics

When studying M.Sc. Mathematics, this module can be attended in the study area Compulsory Elective Modules in Mathematics.

The module can also be used in other study programs (export module).

The module is assigned to Pure Mathematics. Further information on eligibility can be found in the description of the study area.
