Split hyperplane sections on smooth polarized $K3$-surfaces

Algebraic Geometry 2025-09-30 v1

Abstract

We study hyperplane sections of smooth polarized K3K3-surfaces that split into unions of lines. We describe the dual adjacency graphs of such sections and find sharp upper bounds on their number. In most cases (starting from degree 66), we also compute all configurations of such sections.
