Noetherian rings of low global dimension and syzygetic prime ideals

Commutative Algebra 2019-10-04 v1

Abstract

Let RR be a Noetherian ring. We prove that RR has global dimension at most two if, and only if, every prime ideal of RR is of linear type. Similarly, we show that RR has global dimension at most three if, and only if, every prime ideal of RR is syzygetic. As a consequence, one derives a characterization of these rings using the Andr\'e-Quillen homology.
