SUMMARY:The smooth closing lemma for area-preserving surface diffeomorphisms
DESCRIPTION:Speaker: Boyu Zhang\, Princeton University \nTitle: The smooth closing lemma for area-preserving surface diffeomorphisms \nAbstract: 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.
