Simplicial bounded cohomology and stability

Thorben Kastenholz, Robin J. Sroka

We introduce a set of combinatorial techniques for studying the simplicial bounded cohomology of semi-simplicial sets, simplicial complexes and posets. We apply these methods to pr…

A presentation of symplectic Steinberg modules and cohomology of $Sp_{2 n} (Z)$

Benjamin Brück, Peter Patzt, Robin J. Sroka

Borel-Serre proved that the integral symplectic group $Sp_{2 n} (Z)$ is a virtual duality group of dimension $n^{2}$ and that the symplectic Steinberg module $\…

Apartment classes of integral symplectic groups

Benjamin Brück, Robin J. Sroka

In this note we present an alternative proof of a theorem of Gunnells, which states that the Steinberg module of $S p_{2n} (Q)$ is a cyclic $\operatorname{Sp_…
