Intersection theory for Whitney towers


Speaker: Peter Teichner, UC Berkeley
Location: 2112 MSB
Start time: Tue, May 5 2009, 4:10PM

We'll first explain joint work with Rob Schneiderman on a geometric interpretation of Milnor invariants in terms of intersection trees of Whitney towers. Then we shall assume a conjecture of Levine and a geometric conjecture to completely compute the filtration of classical links induced by Whitney towers (of various orders). The latter is joint with Jim Conant and Rob Schneiderman.
