Teichmüller polynomials, Alexander polynomials and finite covers of surfaces
Thomas Koberda
In this note we explore a connection between finite covers of surfaces and the Teichmüller polynomial of a fibered face of a hyperbolic 3--manifold. We consider the action of a hom…
The action of mapping classes on nilpotent covers of surfaces
Thomas Koberda
Let be a surface whose interior admits a hyperbolic structure of finite volume. In this paper, we show that any infinite order mapping class acts with infinite order on the hom…
Entropy of automorphisms, homology and the intrinsic polynomial structure of nilpotent groups
Thomas Koberda
We study the word length entropy of automorphisms of residually nilpotent groups, and how the entropy of such group automorphisms relates to the entropy of induced automorphisms on…
Embedability between right-angled Artin groups
Sang-hyun Kim, Thomas Koberda
In this article we study the right-angled Artin subgroups of a given right-angled Artin group. Starting with a graph $\gam$, we produce a new graph through a purely combinatorial p…
