Bridge number and diagrams of surface links in the 4-sphere
by
Alex Zupan

Coauthors: David Gay, Jeffrey Meier

Adapting work of Gay and Kirby on 4-manifolds, we introduce the notion of a bridge trisection for a surface link, which may be viewed as an analogue of a classical bridge decomposition for a link in the 3-sphere. A bridge trisection yields a presentation of a surface link as a triple of planar tangle diagrams. We discuss evidence that these triples can be used to convert classical knot invariants to dimension 4.
