A family of good Gorenstein local rings

Following Roos, we say that a local ring $R$ is good if all finitely generated $R$-modules have rational Poincare series over $R$, sharing a common denominator. Rings with the Backelin-Roos property and generalised Golod rings are good due to results of Levin and Avramov respectively. Let $R$ be an Artinian Gorenstein local ring. The ring $R$ is shown to have the Backelin-Roos property if $R/ soc(R)$ is a Golod ring. Furthermore the ring $R$ is generalised Golod if and only if $R/ soc(R)$ is so. We explore when connected sums of Artinian Gorenstein local rings are good. We provide a uniform argument to show that stretched, almost stretched Gorenstein rings are good and show further that the Auslander-Reiten conjecture holds true for such rings. We prove that Gorenstein rings of multiplicity at most eleven are good. We recover a result of Rossi-Şega on the good property of compressed Gorenstein local rings in a stronger form by a shorter argument.
