CARMA SEMINAR Speaker: Assoc Prof Murray Elder, CARMA, The University of Newcastle Title: Totally disconnected groups from Baumslag-Solitar groups Location: Room V129, Mathematics Building (Callaghan Campus) The University of Newcastle Time and Date: 4:00 pm, Thu, 20th Sep 2012 Abstract: We consider the problem of characterising embeddings of an abstract group into totally disconnected locally compact (tdlc) groups. Specifically, for each pair of nonzero integers $m,n$ we construct a tdlc group containing the Baumslag-Solitar group $BS(m,n)$ as a dense subgroup, and compute the scales of elements and flat rank of the tdlc group. This is joint work with George Willis. [Permanent link]
