Abstract:

Let R be a noetherian prime p.i. ring, C the center of R and $\bar C$ its normalization. It is proved that R is integral over its center iff $\bar C$ is a Krull domain. We also give a simple proof for the following theorem [7]: The normalization of a commutative noetherian domain is Krull.
