Learning outcome

This course will enable the participants to work with basic topological concepts and methods.  At the end of the course, the students are expected to have attained:


  • understand and assimluate the concepts and methods of the main course topics including basic definitions and theorems
  • understand secondary topics covered in the specific course



  • determine properties of a topological space such as Hausdorffness, countability, (path) connectedness, (local) compactness
  • construct new spaces as subspaces, quotient spaces and product spaces of known ones



  • analyze concrete topological spaces using acquired knowledge and skills
  • relate the theory of topological spaces and continuous maps to specific settings in past and future math courses


5 hours of lectures and 3 hours of exercises per week for 7 weeks.

Type of assessment
Continuous assessment
Written examination, 3 hour under invigilation
A complete evaluation of weekly work (weighted 50%) and a written 3 hour ‘closed-book’ final exam (weighted 50%) constitute the basis for assessment.
Only certain aids allowed

All aids allowed for the weekly homework. No books and no electronic aids are allowed for the 3 hours final exam. Personally created handwritten notes on paper are allowed.
