| Oct 21, 2010 at 12:39 | comment | added | Colin Reid | I've never seen this before, but it looks like a fascinating idea. Are you taking this as a subgroup of the Cartesian product, or a subgroup of the ultraproduct? One guess I would make is that it won't be possible to put a nice topology on this construction, in the way that e.g. profinite groups have a nice topology. | |
