Large Non-Planar Graphs and an Application to Crossing-Critical Graphs

Guoli Ding, Bogdan Oporowski, Robin Thomas +1

We prove that, for every positive integer k, there is an integer N such that every 4-connected non-planar graph with at least N vertices has a minor isomorphic to K_{4,k}, the grap…

Maslov index, Lagrangians, Mapping Class Groups and TQFT

Patrick M. Gilmer, Gregor Masbaum

Given a mapping class f of an oriented surface Sigma and a lagrangian lambda in the first homology of Sigma, we define an integer n_{lambda}(f). We use n_{lambda}(f) (mod 4) to des…
