Geometry and Topology Seminar: Smooth surfaces in 4-space and me.
4 December 2014 13:00 in CM221
This is a report on joint work with Lukas Lewark (once of Durham, now of Bern). No prior knowledge assumed. I'll talk about the smooth "4-ball genus" of a knot - the history of its study, where "quantum" invariants fit into that story, and the weird and wonderful phenomena that we have recently observed.
