Speaker: Augustin Banyaga, Penn State

Abstract: We show that the symplectic displacement energy of a non-empty open subset of a compact symplectic manifold (i.e. the infimum of the Hofer-like norms of symplectic diffeomorphisms that displace the subset) is a strictly positive number. We apply this fact to prove a result that justifies the introduction of the notion of strong symplectic homeomorphisms. This is a joint work with David Hurtubise and Peter Spaeth.
