K3 surfaces and orthogonal modular forms
We determine explicit generators for the ring of modular forms associated with the moduli spaces of K3 surfaces with automorphism group (Z/2Z)2(\mathbb {Z}/2\mathbb {Z})^2 and of Picard rank 13 and higher. The K3 surfaces in question carry a canonical Jacobian elliptic fibration and the modular form...

| Zusammenfassung: | We determine explicit generators for the ring of modular forms associated with the moduli spaces of K3 surfaces with automorphism group (Z/2Z)2(\mathbb {Z}/2\mathbb {Z})^2 and of Picard rank 13 and higher. The K3 surfaces in question carry a canonical Jacobian elliptic fibration and the modular form generators appear as coefficients in the Weierstrass-type equations describing these fibrations. |
