论文摘要
在本文中，我们研究了Picard第四的K3表面的$ 14 $的几何形状，其中有限的自动形态小组，其Néron-Severi lattices已由è.b。分类。温伯格。我们提供投影模型，确定Cox环的生成集的程度，在某些情况下，我们证明了相关模量空间的不合理性。
In this paper we study the geometry of the $14$ families of K3 surfaces of Picard number four with finite automorphism group, whose Néron-Severi lattices have been classified by È.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.
