On log del Pezzo surfaces in large characteristic (1601.03583v2)
Published 14 Jan 2016 in math.AG
Abstract: We show that any Kawamata log terminal del Pezzo surface over an algebraically closed field of large characteristic is globally F-regular or it admits a log resolution which is liftable to characteristic zero. As a consequence, we prove the Kawamata-Viehweg vanishing theorem for klt del Pezzo surfaces of large characteristic.
