Positive braid knots of maximal topological 4-genus

Geometric Topology 2017-12-01 v2

Abstract

We show that a positive braid knot has maximal topological 4-genus exactly if it has maximal signature invariant. As an application, we determine all positive braid knots with maximal topological 4-genus and compute the topological 4-genus for all positive braid knots with up to 12 crossings.
