CMSA Interdisciplinary Science Seminar: The smooth closing lemma for area-preserving surface diffeomorphisms
December 16, 2021 9:00 am - 10:00 am
via Zoom Video Conferencing
Boyu Zhang - Princeton University
In this talk, I will introduce the smooth closing lemma for area-preserving diffeomorphisms on surfaces. The proof is based on a Weyl formula for PFH spectral invariants and a non-vanishing result of twisted Seiberg-Witten Floer homology. This is joint work with Dan Cristofaro-Gardiner and Rohil Prasad.
