We establish lower bounds on the dimensions in which arithmetic groups with torsion can act on acyclic manifolds and homology spheres. The bounds rely on the existence of elementary p-groups in the groups concerned. In some cases, including Sp(2n,Z),

We consider discontinuous operations of a group $G$ on a contractible $n$-dimensional manifold $X$. Let $E$ be a finite dimensional representation of $G$ over a field $k$ of characteristics 0. Let $\mathcal{E}$ be the sheaf on the quotient space $Y=G

In 1970 Alexander Grothendieck [6] posed the following problem: let Γ1 and Γ2 be finitely presented, residually finite groups, and let u : Γ1 → Γ2 be a homomorphism such that the induced map of profinite completions û: Γ̂1 → Γ̂2 is an is

Let be an irreducible lattice in PSL2(R)d (d ∈ N) and z a point in the d-fold direct product of the upper half-plane. We study the discrete set of componentwise distances D( , z) ⊂ Rd defined in (2). We prove asymptotic results on the number of
