  • Fundamentals of set-theoretic topology: Open sets, continuous mappings.
  • Bases, construction of topological spaces, connectivity, separation properties
  • Compactness and metrizability: Central theorems on compactness,
  • metrizability conditions
  • Homotopy,: homotopy classes and equivalence, mappings of and in spheres
  • Coverings: lifting properties, fundamental group

Qualification Goals

The students

  • understand basic principles of topological structures and recognize that such structures can be found in many parts of mathematics,
  • practice the axiomatic approach and train their abstraction skills,
  • develop a deeper understanding of the implications of elementary conditions on a topological space,
  • practice mathematical methods (development of mathematical intuition and its formal justification in proofs),
  • improve their oral communication skills in the recitation class by practicing free speech in front of an audience and during discussions.


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.
