An inequality on diagonalF-thresholds over standard-graded completeintersection rings

Abstract

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