| Apr 16, 2021 at 15:03 | comment | added | Emil Jeřábek | @HarryAltman That’s not the only error, though. It is also not true that every complete ordered field has to include $\mathbb R$ (e.g., consider the Hahn series field $\mathbb Q[[t^{\mathbb Z}]]$, which, incidentally, is sequential). | |
| Jan 15, 2013 at 1:50 | comment | added | Harry Altman | I wouldn't say its "nonsense" -- there's a perfectly sensible notion of "completeness" and "completion" for ordered fields. It just isn't detectable via sequences in general; I'd say that's the real error here. | |
