Rational surfaces in index-one Fano hypersurfaces

Algebraic Geometry 2007-05-23 v1

Abstract

We give the first evidence for a conjecture that a general, index-one, Fano hypersurface is not unirational: (i) a general point of the hypersurface is contained in no rational surface ruled, roughly, by low-degree rational curves, and (ii) a general point is contained in no image of a Del Pezzo surface.
