After Gromov’s foundational work in 1985, problems of symplectic embeddings lie in the heart of symplectic geometry.

# Symplectic Geometry Seminar

The seminar meets each Friday at 1:30 pm, with the venue alternating between Fine Hall 322 at Princeton and Simonyi Hall at the IAS. This seminar also has their own webpage. *Please click on seminar title for complete abstract. *

### Seminar Events

##### On the Gromov width of polygon spaces

University of Pavia

##### Cyclic homology and S^1-equivariant symplectic cohomology

In this talk, we study two natural circle actions in Floer theory, one on symplectic cohomology and one on the Hochschild homology of the Fukaya category. We show that the geometric open-closed string map between these two complexes is S^1-equivariant, at a suitable chain level.

##### On normal crossings symplectic divisors

I will describe purely symplectic notions of normal crossings divisor and configuration. They are compatible with the existence of the desired auxiliary almost Kahler structures, provided ``existence" is suitably interpreted.
