| Mar 2, 2012 at 16:22 | comment | added | Terry Tao | Perhaps one could start with a single free subgroup of SU(2) with algebraic coefficients (which can be constructed by a ping-pong argument in some p-adic topology, as in the standard demonstration of the Banach-Tarski paradox), and work with subgroups of that free subgroup (which are automatically themselves free, by the Nelson-Schrier theorem). As the free subgroup is dense in the Archimedean topology, I would imagine that the set of independent generators g_1,...,g_k in it would also be dense. | |
