Mori dream K3 surfaces of Picard number four: projective models and Cox rings

Algebraic Geometry 2020-11-03 v1

Abstract

In this paper we study the geometry of the 1414 families of K3 surfaces of Picard number four with finite automorphism group, whose N\'eron-Severi lattices have been classified by \`E.B. Vinberg. We provide projective models, we identify the degrees of a generating set of the Cox ring and in some cases we prove the unirationality of the associated moduli space.
