Riccardo Pedrotti, RLM 12.166: The Floer homology of a Dehn twist
Tuesday, February 25, 2020, 03:45pm - 04:45pm
In this talk, I'll try to motivate the usefulness of tools provided by Floer homology to prove properties of elements in the Mapping class group of oriented surfaces of genus at least 2. Floer homology is an infinite dimensional version of Morse homology which in our setting turns out to be quite tractable. I'll use a collection of tools from many different fields in geometry, analysis and topology in order to get results in (very) low dimensional topology. This turns out to be quite the analogy with our Jr. Geometry seminar and its very ample family of topics
