Polarized cylinders in Du Val del Pezzo surfaces of degree two

Algebraic Geometry 2026-05-15 v3

Abstract

Let SS be a del Pezzo surface with at worst Du Val singularities of degree 22 such that SS admits an (KS)(-K_S)-polar cylinder. In this article, we construct an HH-polar cylinder for any ample Q\mathbb{Q}-divisor HH on SS.
