Person in charge of the module's outline Prof. Dr. Ilka Agricola


  • Topological spaces and manifolds
  • Elementary properties of topological spaces: compactness, orientability, boundary. Many examples: Möbius band, Klein's bottle, projective space etc.
  • Classification of surfaces, genus of a surface, triangulations, Boy's surface
  • Euler Characteristic and Euler's polyhedron theorem
  • Fundamental group, mapping degree and coverings

Qualification Goals

The students shall

  • understand basic principles of topological structures and recognize that such structures can be found in many parts of mathematics,
  • practice axiomatic procedures and train their abstraction skills,
  • practice mathematical working methods (development of mathematical intuition and its formal justification, proof techniques),
  • improve their oral communication skills in the exercises by practicing free speech in front of an audience and during discussion.

Please note:

This page describes a module according to the latest valid module guide in Winter semester 2018/19. 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.
