Seminar: Symplektische Topologie / Symplectic Topology — Wintersemester 2017-18, 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.

The seminar will meet this semester on Mondays, 15:00-17:00 (c.t.) in room 1.114 at Rudower Chaussee 25 (subject to change). It will occasionally be preempted by the Berlin-Hamburg Symplectic Geometry Seminar.

Organizational note: The first Monday this semester is a dies academicus, but we will nonetheless have a special meeting of the seminar on that day since there is a visiting speaker. The first official meeting of the seminar for this semester will thus be on October 23, when we will discuss plans for the rest of the semester. Students looking for further information about the seminar in the mean time should feel free to contact Profs. Mohnke or Wendl.

Speaker: Oliver Fabert (VU Amsterdam)
Topic: J-holomorphic curves in infinite dimensions
Abstract: Many important PDEs can be viewed as infinite-dimensional Hamiltonian systems. Although modern Hamiltonian dynamics has started with P. Rabinowitz' work on nonlinear wave equations, the infinite-dimensional case has received much less attention --- partly as the J-holomorphic curve techniques are not readily available. In my talk I will present an efficient model-theoretic method to transfer results from finite to infinite dimensions. I will illustrate its use by proving a nonsqueezing result for smooth infinite-dimensional Hamiltonian flows and a generalized Arnold conjecture for nonlinear Schrödinger equations.
