By Margulis-Soifer, lattices in Sl(n,C) or Sl(n,R) have infinite index maximal subgroups. They asked: are these (surprising) subgroups never finitely generated? Using the recent resolution of the Marden conjecture, this can be answered for Sl(2,C). This is related to the pro-normal topology, pro-density, and the (hard) property LERF. This is joint work with Y. Glasner and J. Souto.
