Titel C^0 limits of Hamiltonian paths and spectral invariants
Referent:in, Affiliation Sobhan Seyfaddini, ENS Paris, France
Datum, Zeit 5. November 2012, 15:15-16:30
Ort HG G 43
Abstract After briefly reviewing spectral invariants, I will write down an estimate, which under certain assumptions, relates the spectral invariants of a Hamiltonian to the C^0-distance of its flow from the identity. Time permitting I will present a few applications to Hofer geometry.

Titel Counting Toric Actions
Referent:in, Affiliation Yael Karshon, University of Toronto
Datum, Zeit 19. November 2012, 15:15-16:30
Ort HG G 43
Abstract In how many different ways can a two-torus act on a given simply connected symplectic four-manifold? It is known that number of inequivalent torus actions is finite, but the (``soft") proof of this fact does not give this number. Together with Liat Kessler and Martin Pinsonnault, we reduce this counting question to combinatorics by expressing the manifold as a symplectic blowup in a way that is compatible with all the torus actions simultaneously. This uses the theory of pseudoholomorphic curves.
