Sur une classe de formes biquadratiques semi-definies positives

Continuing the study of positive semidefinite biquadratic forms on Rm × Rn ([1], [9] and [10]), we characterize those among them that are the sum of squares of bilinear forms.

A Complex Hyperbolic Structure for Moduli of Cubic Surfaces

We show that the moduli space M of marked cubic surfaces is biholomorphic to (B −H)/Γ0 where B is complex hyperbolic four-space, where Γ0 is a specific group generated by complex reflections, and where H is the union of reflection hyperplanes for Γ0. Thus M has a complex hyperbolic structure, i.e., an (incomplete) metric of constant holomorphic sectional curvature. Une structure hyperbolique co...

We show that the moduli space M of marked cubic surfaces is biholomorphic to (B 4 ? H)=? 0 where B 4 is complex hyperbolic four-space, where ? 0 is a speciic group generated by complex reeections, and where H is the union of reeection hyperplanes for ? 0. Thus M has complex hyperbolic structure, i.e., an (incomplete) metric of constant holomorphic sectional curvature. Une structure hyperbolique...
