On Kummer-like surfaces attached to singularity and modular forms

We study a family of lattice polarized K3 surfaces which is an extension of the family of Kummer surfaces derived from principally polarized Abelian surfaces. Our family has two special properties. First, it is coming from a resolution of a simple K3 singularity. Second, it has a natural parameterization by Hermitian modular forms of four complex variables. In this paper, we show two results: (1) we determine the transcendental lattice and the Neron-Severi lattice of a generic member of our family. (2) We give a detailed description of the double covering structure associated with our K3 surfaces.

We studied a family of lattice polarized K3 surfaces, which extends from the family of Kummer surfaces derived from principally polarized Abelian surfaces. Our family has two special properties: it originates from the resolution of a simple K3 singularity, and it can be parameterized naturally by Hermitian modular forms with four complex variables. In this paper, we presented two results: (1) determination of the transcendental lattice and the Neron-Severi lattice of a generic member in our family; (2) detailed description of the double covering structure associated with our K3 surfaces.
