A new proof of finiteness of maximal arithmetic reflection groups

David Fisher, Sebastian Hurtado

We give a new proof of the finiteness of maximal arithmetic reflection groups. Our proof is novel in that it makes no use of trace formulas or other tools from the theory of automo…

Continuity of discrete homomorphisms of diffeomorphism groups

Sebastian Hurtado

Let $M$ and $N$ be two closed $C^{\infty}$ manifolds and let $Diff_{c} (M)$ denote the group of $C^{\infty}$ diffeomorphisms isotopic to the identity. We prove that any (discre…
