| Oct 20, 2019 at 8:53 | comment | added | YCor | @PeterShor I think I can answer positively your question (for arbitrary non-principal ultraproducts of sequences of finite cyclic groups), if you ask it separately (it doesn't really fit in a comment). | |
| Sep 9, 2011 at 22:01 | comment | added | M T | @Peter Shor: the ultrapower of the reals (i.e. the hyperreals) is independent of the non-principal ultrafilter you choose...so long as you believe GCH. Maybe something similar is needed here. | |

| Aug 31, 2010 at 15:38 | comment | added | Peter Shor | Is this ultraproduct unique (i.e., it doesn't depend on the ultrafilter)? It seems to me as though it should be, but I can't prove it. Then again, I don't have much experience with these things. | |
