In this talk, we discuss our work in progress about how degeneration of the divisor at infinity into a normal crossing divisor affects the symplectic homology of an affine variety.

# 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. *

##### Equivalent notions of high-dimensional overtwistedness

In recent joint work with Borman and Eliashberg, a new definition of overtwisted contact structures was given for high-dimensional contact manifolds, which were then classified up to isotopy.
