    Here's one proof. Let R be a Dedekind ring and assume that the prime ideals are p1,pn. Then p21,p2,pn are coprime.

    One Prime Ideal. Let R be a dedekind domain with one prime ideal P. All ideals are powers of P, and are linearly.

    Why did my reputation suddenly increase by points? It is well known that a Dedekind domain is noetherian and so it's maximal spectrum is noetherian space as a subspace of Zariski topology. From the definition I read it is not immediate to me why those ideals are maximal.
