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…
Distance in the curve graph
Ursula Hamenstaedt
We estimate the distance in the curve graph of a surface S of finite type using Teichmueller geodesics and assuming to be able to detect curves of distance at least three.
Asymptotic dimension and the disk graph I
Ursula Hamenstaedt
For a 3-manifold M and a subsurface of the boundary of M with empty or incompressible boundary we use surgery to identify a graph whose vertices are disks with boundary in X an…
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…
