Rational contact surgery and Heegaard Floer invariants

Symplectic geometry and topology

20 October 14:00 - 15:00

Thomas Mark - University of Virginia

I’ll describe some recent joint work with Bulent Tosun that shows the contact invariant in Heegaard Floer homology behaves “naturally” under certain contact surgery operations. As an application we give a complete description of the contact invariant of a contact structure obtained by positive rational contact surgery on a Legendrian knot in the standard 3-sphere.
