A Complex Ball Uniformization of the Moduli Space of Cubic Surfaces via Periods of K3 Surfaces

In this paper we show that the moduli space of nodal cubic surfaces is isomorphic to a quotient of a 4-dimensional complex ball by an arithmetic subgroup of the unitary group. This complex ball uniformization uses the periods of certain K3 surfaces which are naturally associated to cubic surfaces. A similar uniformization is given for the covers of the moduli space corresponding to geometric ma...

Characterizations of Slant Ruled Surfaces in the Euclidean 3-space

In this study, we give the relationships between the conical curvatures of ruled surfaces generated by the unit vectors of the ruling, central normal and central tangent of a ruled surface in the Euclidean 3-space E^3. We obtain differential equations characterizing slant ruled surfaces and if the reference ruled surface is a slant ruled surface, we give the conditions for the surfaces generate...

Classification of Cubic Surfaces with Computational Methods

The aim of the paper is the study the orbits of the action of PGL 4 on the space P 19 of the cubic surfaces of P 3 , i.e. the classiication of cubic surfaces up to projective motions. All the cubic surfaces with nitely many lines are parametrized by a variety Q P 19 , explicitely constructed as the union of (22) disjoint irreducible components which are either points or open subsets of linear s...

A W (E6)-equivariant projective embedding of the moduli space of cubic surfaces

An explicit projective embedding of the moduli space of marked cubic surfaces is given. This embedding is equivariant under the Weyl group of type E6. The image is defined by a system of linear and cubic equations. To express the embedding in a most symmetric way, the target would be 79-dimensional, however the image lies in a 9-dimensional linear subspace. 1 The moduli space of cubic surfaces ...
