Finitistic test ideals on numerically $\mathbb{Q}$-Gorenstein varieties (1709.09383v3)
Published 27 Sep 2017 in math.AC and math.AG
Abstract: We prove that the finitistic test ideal $\tau_{\rm fg}(R, \Delta, \mathfrak{a}t)$ coincides with the big test ideal $\tau_{\rm b}(R, \Delta, \mathfrak{a}t)$ if the pair $(R,\Delta)$ is numerically log $\mathbb{Q}$-Gorenstein.
