# Are unique prime ideal factorization domains noetherian?

Let $$A$$ be a domain satisfying the following condition:

If $$\mathfrak p_1,\dots,\mathfrak p_k$$ are distinct nonzero prime ideals of $$A$$, and if $$m$$ and $$n$$ are distinct elements of $$\mathbb N^k$$, then we have $$\mathfrak p_1^{m_1}\cdots\mathfrak p_k^{m_k}\ne\mathfrak p_1^{n_1}\cdots\mathfrak p_k^{n_k}.$$

Is $$A$$ necessarily noetherian?

This question is motivated by these outstanding answers of user26857 and Julian Rosen.

user26857's answer shows that noetherian domains do satisfy the above condition, whereas Julian's answer shows that many non-noetherian domains do not satisfy it.

• It's true for $1$-dimensional valuation domains. Is it true for valuation domains in general? Jan 3, 2019 at 19:26
• I think there are 1-dimensional valuation domains such that $m^2=m$. Jan 3, 2019 at 23:59
• Yes exactly. A $1$-dimensional valuation domain is Noetherian iff its max ideal is not idempotent iff it satisfies the property in question. Jan 4, 2019 at 0:15

Let's call domains having this property $$UPIF$$-domains, as in your first post.

Observe that a domain which is locally $$UPIF$$ is $$UPIF$$.

Indeed, given $$\mathfrak p_1^{m_1}\cdots\mathfrak p_k^{m_k}=\mathfrak p_1^{n_1}\cdots\mathfrak p_k^{n_k}$$ we can localize at each of the $$\mathfrak{p_i}$$ one at a time and use the assumption that $$D_{\mathfrak{p_i}}$$ is $$UPIF$$ to deduce that $$m_i = n_i$$.

A locally Noetherian domain is $$UPIF$$.
