Abstract

Let $k$ be a commutative Noetherian ring, and $k[S]$ the polynomial ring with indeterminates parameterized by elements in a set $S$. We show that $k[S]$ is Noetherian up to actions of permutation groups on $S$ satisfying certain combinatorial conditions. Moreover, there is a special linear order on every infinite $S$ such that $k[S]$ is Noetherian up to the action of the order-preserving permutation group, and the existence of such a linear order is equivalent to the Axiom of Choice. These Noetherian results are proved via a sheaf theoretic approach and the work of Nagel-R\"{o}mer.
