Residual properties of 3-manifold groups I: Fibered and hyperbolic 3-manifolds
Thomas Koberda
Let be a prime. In this paper, we classify the geometric 3-manifolds whose fundamental groups are virtually residually . Let be a virtually fibered 3-manifold. It is…
Representations of Galois Groups on the Homology of Surfaces
Thomas Koberda, Aaron Michael Silberstein
Let be a finite Galois cover, possibly branched, with Galois group . We are interested in the structure of the cohomology of as a module over . We treat the c…
Effective indices of subgroups in Baumslag--Pride groups with free quotients
Thomas Koberda
Given a group with at least two more generators than relations, we give an effective estimate on the minimal index of a subgroup with a nonabelian free quotient. We show that the i…
Asymptotic linearity of the mapping class group and a homological version of the Nielsen-Thurston classification
Thomas Koberda
We study the action of the mapping class group on the real homology of finite covers of a topological surface. We use the homological representation of the mapping class to constru…
