Hauptseminar Symplektische Geometrie

There are various results that connect topological properties of special contact manifolds with the topological entropy of their Reeb flows, see for example Macarini--Schlenk, Frauenfelder--Labrousse--Schlenk, Alves or Alves--Meiwes. The proof of results of this type uses growth (in various senses) of symplectic homology or Rabinowitz--Floer homology. I will explain how to push one of these results from the realm of Reeb flows to positive contactomorphisms (i.e. time-dependent Reeb flows). I will also explain why positive contactomorphisms seem to be the maximal class of maps for which such a kind of result holds true.
