Abstract:

In this note it is proved that if $R$ is an integral domain the set of valuation ideals of $R$ is closed under intersection if and only if the integral closure of $R$ is a valuation ring. Let $S$ be a domain which is integrally dependent on $R$ and contains the integral closure of $R$. Then the set of valuation ideals of $R$ is the same as the set of ideals of $R$ which contract from ideals of $S$ if and only if the set of valuation ideals of $R$ is closed under intersection.
