Prerequisites: Diskrete Geometrie I and Algebra I.


The study of realization spaces of polytopes is a classical topic in geometric combinatorics at the interface between discrete and real algebraic geometry. We will begin with classical constructions and results, and then focus on recent advances.
Topics of the course are:
  • Main definitions and constructions
  • Three-dimensional vs higher dimesional polytopes
  • Comparison of different models
  • Recent advances
