Noncoherence of some lattices in Isom(Hn)

Michael Kapovich, Leonid Potyagailo, Ernest Vinberg

We prove noncoherence of certain families of lattices in the isometry group of the hyperbolic n-space for n greater than 3. For instance, every nonuniform arithmetic lattice in SO(…

Dense embeddings of surface groups

Emmanuel Breuillard, Tsachik Gelander, Juan Souto +1

We discuss dense embeddings of surface groups and fully residually free groups in topological groups. We show that a compact topological group contains a nonabelian dense free grou…

On the cohomology of the holomorph of a finite cyclic group

Johannes Huebschmann

The mod 2 cohomology algebra of the holomorph of any finite cyclic group whose order is a power of 2 is determined.
