Isoperimetric inequalities for the handlebody groups
Ursula Hamenstädt, Sebastian Hensel
We show that the mapping class group of a handlebody of genus at least 2 has a Dehn function of at most exponential growth type.

Spheres and Projections for
Ursula Hamenstädt, Sebastian Hensel
The outer automorphism group Out(F_2g) of a free group on 2g generators naturally contains the mapping class group of a punctured surface as a subgroup. We define a subsurface proj…

The geometry of the handlebody groups I: Distortion
Ursula Hamenstädt, Sebastian Hensel
We show that the mapping class group of a handlebody of genus at least 2 (with any number of marked points or spots) is exponentially distorted in the mapping class group of its bo…
