Milnor's triple linking numbers and C-complexes (Matthias Nagel, Université du Québec à Montréal)

01.06.2017 14:15

We recall how to compute Milnor's triple linking numbers from a C-complex. We then relate these invariants to fillability of two link exteriors, and the question when two links admit equivalent C-complexes. This extends a theorem of Roth-Davis to include also links with nonvanishing linking numbers. This is joint work with P. Orson and M. Powell.
