Products of ideals and Golod rings

Abstract

In this paper, we study conditions guaranteeing that a product of ideals defines a Golod ring. We show that for a 3 3 -dimensional regular local ring (or 3 3 -variable polynomial ring) ( R , m ) (R, \mathfrak {m}) , the ideal I m I \mathfrak {m} always defines a Golod ring for any proper ideal I R I \subset R . We also show that non-Golod products of ideals are ubiquitous; more precisely, we prove that for any proper ideal with grade 4 \geqslant 4 , there exists an ideal J I J \subseteq I such that I J IJ is not Golod. We conclude by showing that if I I is any proper ideal in a 3 3 -dimensional regular local ring and a I \mathfrak {a} \subseteq I a complete intersection, then a I \mathfrak {a} I is Golod.
