The Geometry of the Handlebody Groups II: Dehn functions

Group Theory 2018-05-01 v1 Geometric Topology Metric Geometry

Abstract

We show that the Dehn function of the handlebody group is exponential in any genus g3g\geq 3. On the other hand, we show that the handlebody group of genus 22 is cubical, biautomatic, and therefore has a quadratic Dehn function.
