Seminar: Symplektische Geometrie / Symplectic Geometry — Sommersemester 2019, HU Berlin

This is a working group seminar run by Klaus Mohnke and Chris Wendl on recent developments in symplectic geometry. Participants are expected to be familiar with the basics of symplectic geometry, including some knowledge of holomorphic curves and/or Floer-type theories. The seminar is conducted in English.

We will switch the time of the seminar this semester to Mondays, 13:00-15:00 (c.t.) in room 1.315 at Rudower Chaussee 25. It will occasionally be preempted by the Berlin-Hamburg Symplectic Geometry Seminar.

RUD 25, Room 1.315
Speaker: Marc Kegel
Topic: Open questions about open books
Abstract: In this talk, I would like to survey the close connection between open books and contact structures. Special attention will be paid to some open questions. No previous knowledge about contact structures or open books is assumed.

Topic: Introduction to spinal open books
Abstract: Spinal open books are a generalization of open book decompositions in which the binding is replaced by something that may have more nontrivial topology. Just like an open book, a spinal open book on a closed 3-manifold determines a compatible contact structure up to isotopy. My goal in this talk will be to introduce the basic notions and then sketch two applications of a topological nature: (1) the construction of symplectic cobordisms via "spine removal surgery" and resulting proof that certain contact manifolds are not symplectically fillable; (2) a reinterpretation of Bourgeois's classic result that for every contact manifold, the product of that manifold with the 2-torus also admits a contact structure.
