The Geometry of the Handlebody Groups II: Dehn Functions

Hamenstaedt, Ursula und Hensel, Sebastian (2021): The Geometry of the Handlebody Groups II: Dehn Functions. In: Michigan Mathematical Journal, Vol. 70, No. 1: pp. 23-53

Abstract

We show that the Dehn function of the handlebody group is exponential in any genus g >= 3. On the other hand, we show that the handlebody group of genus 2 is cubical and biautomatic and therefore has a quadratic Dehn function.
