| Feb 24, 2011 at 15:39 | comment | added | Georges Elencwajg | As an aside (that absolutely doesn't answer the question ...) let me recall that between the innocent-looking rings $\mathbb Z$ and $\mathbb Q$ there is a continuum of rings, all of them principal ideal domains, obtained by inverting arbitrary subsets of the prime numbers | |

| Feb 24, 2011 at 14:30 | comment | added | Georges Elencwajg | Dear Laurent, I don't think you can say "more generally" because Kevin's example consists of convergent power series, whereas yours are of algebraic nature. | |
| Feb 24, 2011 at 12:46 | comment | added | Laurent Moret-Bailly | More generally, there are lots of discrete valuation rings arising from geometry (local ring of the generic point of a divisor in a smooth variety); I don't suppose they count as "exotic". | |
