Degree theorems and Lipschitz simplicial volume for non-positively curved manifolds of finite volume
Clara Loeh, Roman Sauer
We study a metric version of the simplicial volume on Riemannian manifolds, the Lipschitz simplicial volume, with applications to degree theorems in mind. We establish a proportion…

A spectral sequence to compute L2-Betti numbers of groups and groupoids
Roman Sauer, Andreas Thom
We construct a spectral sequence for L2-type cohomology groups of discrete measured groupoids. Based on the spectral sequence, we prove the Hopf-Singer conjecture for aspherical ma…

Simplicial volume of Hilbert modular varieties
Clara Loeh, Roman Sauer
The simplicial volume introduced by Gromov provides a topologically accessible lower bound for the minimal volume. Lafont and Schmidt proved that the simplicial volume of closed, l…
