The Golod property for powers of ideals and Koszul ideals

Commutative Algebra 2018-04-06 v2

Abstract

Let SS be a regular local ring or a polynomial ring over a field and II be an ideal of SS. Motivated by a recent result of Herzog and Huneke, we study the natural question of whether ImI^m is a Golod ideal for all m2m\geq 2. We observe that the Golod property of an ideal can be detected through the vanishing of certain maps induced in homology. This observation leads us to generalize some known results from the graded case to local rings and obtain new classes of Golod ideals.
