An inequality on diagonal F -thresholds over standard-graded complete intersection rings

Abstract

In a recent paper, De Stefani and Núñez-Betancourt proved that for a standard-graded F -pure k -algebraR, its diagonal F -threshold c(R) is always at least 􀀀a(R) , where a(R) is the a-invariant. In this paper, we establisha refinement of this result in the setting of complete intersection rings.
