Completions of Countable Excellent Local Rings in Equal Characteristic Zero

Commutative Algebra 2022-08-10 v1

Abstract

We characterize which complete local (Noetherian) rings T containing the rationals are the completion of a countable excellent local ring S. We also discuss the possibilities for the map from the minimal prime ideals of T to the minimal prime ideals of S and we prove some characterization-style results.
