Title Diffeomorphism type of symplectically aspherical fillings
Speaker, Affiliation Kai Zehmisch, Universität Münster
Date, Time 21 March 2016, 15:15-16:30
Location 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.

Title Symplectic homology for cobordisms
Speaker, Affiliation Alex Oancea, Université Pierre et Marie Curie, Paris, France
Date, Time 11 April 2016, 15:15-16:30
Location 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.

Title Legendrian contact homology and forcing of topological entropy
Speaker, Affiliation Dr. Marcelo Alves, Université de Neuchâtel
Date, Time 23 May 2016, 15:15-16:30
Location 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.
