Complexity of Reeb flows via Floer homology/Lecture 1

In these lectures, Professor Schlenk will address the second problem for Hamiltonian and Reeb flows. He also will explain how various Floer homologies (Lagrangian Floer homology, Rabinowitz-Floer homology, Legendrian contact homology) can be used to prove positivity of topological entropy for certain classes of symplectomorphisms and Reeb flows.
