Symplectic hats

Abstract: A hat for a transverse knot in a symplectic cap of a contact 3-manifold is a symplectic surface in the cap whose boundary is the knot. I will talk about existence, obstructions, and properties of hats, with an emphasis on the standard 3-sphere, and about an application to Stein fillings. This is joint work with John Etnyre.
