Tim Römer: Symmetries and local-global principles in discrete geometry

Föreläsare: Tim Römer (University of Osnabrück)
We consider cones and monoids in infinite dimensional spaces which are invariant under actions of symmetric groups. A key idea is to study these objects via associated symmetric chains of cones/monoids in finite dimensional spaces and to formulate related local-global principles. In this talk we discuss recent results and open questions on these topics.
