On the existence of parameterized noetherian rings

Rings and Algebras 2025-04-15 v1

Abstract

A ring RR is called left strictly (<α)(<\aleph_{\alpha})-noetherian if α\aleph_{\alpha} is the minimum cardinal such that every ideal of RR is (<α)(<\aleph_{\alpha})-generated. In this note, we show that for every singular (resp., regular) cardinal α\aleph_{\alpha}, there is a valuation domain DD, which is strictly (<α)(<\aleph_{\alpha})-noetherian (resp., strictly (<α+)(<\aleph_{\alpha}^+)-noetherian), positively answering a problem proposed in \cite{Marcos25} under some set theory assumption.
