关于正特征K3曲面锥猜想的注记

A note on the cone conjecture for K3 surfaces in positive characteristic

Max Lieblich, Davesh Maulik

摘要:

证明了对特征p > 2的K3曲面,自同构群作用在具有有理多面体基本区的nef锥上和具有多个轨道的节类上.因此,对于任意非负整数g,在自同构群的作用下,在算术亏格g的曲面上只有2/3个不可约曲线的线性系.

英文摘要:

We prove that, for a K3 surface in characteristic p > 2, the automorphism group acts on the nef cone with a rational polyhedral fundamental domain and on the nodal classes with finitely many orbits. As a consequence, for any non-negative integer g, there are only finitely many linear systems of irreducible curves on the surface of arithmetic genus g, up to the action of the automorphism group.
