On normal subgroups of compact groups (1310.3359v2)
Published 12 Oct 2013 in math.GR
Abstract: Among compact Hausdorff groups G whose maximal profinite quotient is finitely generated, we characterize those that possess a proper dense normal subgroup. We also prove that the abstract commutator subgroup [H,G] is closed for every closed normal subgroup H of G.
