On local delta invariant of del Pezzo surfaces

Published 24 Apr 2023 in math.AG | (2304.12286v2)

Abstract: We complete the classification of local stability thresholds for smooth del Pezzo surfaces of degree~2. In particular, we show that this number is irrational if and only if a unique (-1)-curve passes through the point where we are computing the local invariant.
