The Research Group Topology and Geometry

The research group topology / geometry works on the homotopy theory of various types, such as 

  • homotopic coherence theory
  • ring spectra
  • model categories
  • motivic homotopy theory
  • algebraic K-theory
  • Goodwillie-Calculus

Further information can be found here. The working group Scientific Information is part of the research group.

The research group topology organized the graduate programme Combinatorial Structures in Algebra and Topology  together with the Algebra Group.
