»Rigidity and Flexibility of symplectic embeddings «

Abstract:
I will illustrate a special feature of symplectic geometry, namely the coexistence of rigidity and flexibility, by looking at four symplectic embedding problems in dimension 4, namely embeddings of ellipsoids into a cylinder, a cube, a polydisc and a torus. The answer is very different in each case: total rigidity, total flexibility with a hidden rigidity, and a two-fold subtle transition between them. The talk is based on work by Cristofaro-Gardiner, Frenkel, Latschev, McDuff, Müller and myself.

 

Hierzu ergeht herzliche Einladung.
