Some more combinatorics results on Nagata extensions

Commutative Algebra 2015-02-26 v1

Abstract

We show that lengths of ring extensions are preserved under the formation of Nagata extensions as well as Dobbs-Mullins invariant. We exhibit a new condition for the FIP property be preserved under the formation of Nagata extensions by using arithmetic extensions of rings.
