The mod 2 cohomology rings of SL\_2 of the imaginary quadratic integers
Ethan Berkove, Alexander Rahm
We establish general dimension formulae for the second page of the equivariant spectral sequence of the action of the SL\_2 groups over imaginary quadratic integers on their associ…

A refinement of a conjecture of Quillen
Alexander Rahm, Matthias Wendt
We present some new results on the cohomology of a large scope of SL\_2-groups in degrees above the virtual cohomological dimension; yielding some partial positive results for the…

On the equivariant K-homology of PSL\_2 of the imaginary quadratic integers
Alexander Rahm
We establish formulae for the part due to torsion of the equivariant K-homology of all the Bianchi groups (PSL\_2 of the imaginary quadratic integers), in terms of elementary numbe…
