4:00 pm Monday, January 30, 2017 Topology Seminar: Invariants of Legendrian linksby Caitlin Leverson (Georgia Tech) in HBH 427- Given a plane field dz-ydx in R^3. A Legendrian knot is a knot which at every point is tangent to the plane at the point. One can similarly define a Legendrian knot in any contact 3-manifold (manifold with a plane field satisfying some conditions). In this talk, we will explore Legendrian knots in R^3, J^1(S^1), and #^k(S^1xS^2) as well as a few Legendrian knot invariants. We will also look at the relationships between a few of these knot invariants. No knowledge of Legendrian knots will be assumed.
