Titel Diffeomorphism type of symplectically aspherical fillings
Referent:in, Affiliation Kai Zehmisch, Universität Münster
Datum, Zeit 21. März 2016, 15:15-16:30
Ort HG G 43
Abstract Symplectically aspherical fillings of simply connected contact manifolds that are subcritically Stein fillable are unique up to diffeomorphism. In my talk I will present a proof in dimension at least five and indicate generalisations to classes of contact manifolds with non-trivial fundamental groups. This is joint work with Kilian Barth und Hansjörg Geiges.

Titel Symplectic homology for cobordisms
Referent:in, Affiliation Alex Oancea, Université Pierre et Marie Curie, Paris, France
Datum, Zeit 11. April 2016, 15:15-16:30
Ort HG G 43
Abstract I will present a definition of symplectic homology groups for pairs of Liouville cobordisms with fillings, and explain how these fit into a formalism of homology theory similar to that of Eilenberg and Steenrod. This construction allows to understand form a unified point of view many structural results involving Floer homology groups, and yields new applications. Joint work with Kai Cieliebak.

Titel Legendrian contact homology and forcing of topological entropy
Referent:in, Affiliation Dr. Marcelo Alves, Université de Neuchâtel
Datum, Zeit 23. Mai 2016, 15:15-16:30
Ort HG G 43
Abstract In this talk I will explain how Legendrian contact homology can be used to produce positive lower bounds for the topological entropy of Reeb flows on contact 3-manifolds. As an application I will explain a contact topological generalization of a result of Denvir and Mackay which says that if a Riemannian metric on the two-dimensional torus has a simple contractible closed geodesic then its geodesic flow has positive topological entropy. This is partly joint work with Pedro A. S. Salomão.
