Classification of weak del Pezzo pairs for surfaces

Year: 2024

Type: article

Abstract: A weak del Pezzo surface is a smooth projective surface whose anticanonical divisor [Formula: see text] is nef and big. We generalize this concept to weak del Pezzo pairs for surfaces and classify those with minimal and non-minimal properties.
