DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDS/79/">Top
 ological Entropy of Reeb Flows\, Barcodes and Floer Theory</a>\nby Viktor 
 L. Ginzburg (University of California\, Santa Cruz) as part of Geometry an
 d Dynamics seminar\n\n\nAbstract\nTopological entropy is one of the fundam
 ental invariants of a dynamical \nsystem\, measuring its complexity. In th
 is talk\, we focus on connections \nbetween the topological entropy of a H
 amiltonian dynamical system\, e.g.\, \na Hamiltonian diffeomorphism or a R
 eeb or geodesic flow\, and its \nSymplectic/Floer homology. We recall the 
 definition of barcode entropy — \na Floer theoretic counterpart of topol
 ogical entropy — and discuss \npossible ways to extend it to Reeb flows.
  The talk is based on joint \nwork with Erman Cineli\, Basak Gurel and Mar
 co Mazzucchelli.\n
