Quasipositivity and the Ozsvath and Szabo Contact Invariant

Friday, October 28, 2016, 5:00pm
Ungar Building Room 402


Matthew Hedden proved that a fibered knot being strongly quasipositive is equivalent to the Ozsvath and Szabo contact invariant associated to it being non-zero. I will give background to understand this theorem, as well as give insight into avenues of future research.
