Is a domain $D$, all of whose localizations $D_P$ for $P \in Spec(D)$ are noetherian, itself noetherian ? The question is motivated by proposition 11.5 of Neukirch's Algebraic Number Theory: > Let $\mathfrak{o}$ be a noetherian integral domain. $\mathfrak{o}$ is a Dedekind domain if and only if, for all prime ideals $\mathfrak{p}\neq 0$, the localizations $\mathfrak{o}_\mathfrak{p}$ are discrete valuation rings. If the question above has a positive answer, this proposition would give an unconditioned (i.e. without precondition "noetherian") characterization of Dedekind domains by a local property. By googling I found a counterexample for a ring with zero-divisors: http://math.stackexchange.com/questions/73421/a-non-noetherian-ring-with-all-localizations-noetherian But I couldn't find a counterexample for a domain.
