„Symplectic dynamics of S3“
Prof. Dr. Kai Zehmisch, Justus Liebig Universität Giessen

Aperiodic symplectic flows on open manifolds strongly influence the underlying smooth structure. Equipped with natural boundary conditions such flows defined on knot exteriors lead to a characterization of the 3-sphere in terms of symplectic dynamics. In the first part of my talk I will explain how the diffeomorphism type is related to Eliashberg-Hofer’s filling by holomorphic discs argument. In the second I will indicate a construction of exotic symplectic flows whose defining odd-symplectic form (Hamiltonian structure) extends to a symplectic form on the 4-ball. Minimality properties for these flows are not known as well as properties of Fish-Hofer’s feral holomorphic curves.
