Topology and Geometry Seminar

Title: Dehn surgery, cabling, and contact structures

Speaker: Ken Baker

Abstract: A knot with fibered exterior supports a contact structure. Aside from certain exceptions, each cable of such a knot also has fibered exterior. We'll examine how the supported contact structure changes under the operation of cabling. Adding this to our collection of tools, we may investigate the contact structures supported by dehn surgeries on fibered knots. This is joint work with John Etnyre and Jeremy Van Horn-Morris.
