Singular Del Pezzo Surfaces Whose Universal Torsors Are Hypersurfaces

چکیده

We classify all singular Del Pezzo surfaces of degree three or greater whose universal torsor is an open subset of a hypersurface in affine space. Equivalently, their Cox ring is a polynomial ring with exactly one relation. For all 20 types with this property, we describe the Cox ring in detail.

2 00 6 UNIVERSAL TORSORS OVER DEL PEZZO SURFACES AND RATIONAL POINTS by Ulrich Derenthal & Yuri Tschinkel

— We discuss Manin’s conjecture concerning the distribution of rational points of bounded height on Del Pezzo surfaces, and its refinement by Peyre, and explain applications of universal torsors to counting problems. To illustrate the method, we provide a proof of Manin’s conjecture for the unique split singular quartic Del Pezzo surface with a singularity of type D4.

1 3 Fe b 20 09 COUNTING INTEGRAL POINTS ON UNIVERSAL TORSORS

— Manin’s conjecture for the asymptotic behavior of the number of rational points of bounded height on del Pezzo surfaces can be approached through universal torsors. We prove several auxiliary results for the estimation of the number of integral points in certain regions on universal torsors. As an application, we prove Manin’s conjecture for a singular quartic del Pezzo surface.

Universal Torsors of Del Pezzo Surfaces and Homogeneous Spaces

Let Cox(Sr) be the homogeneous coordinate ring of the blow-up Sr of P 2 in r general points, i.e., a smooth Del Pezzo surface of degree 9 − r. We prove that for r ∈ {6, 7}, Proj(Cox(Sr)) can be embedded into Gr/Pr, where Gr is an algebraic group with root system given by the primitive Picard lattice of Sr and Pr ⊂ Gr is a certain maximal parabolic subgroup.

An Overview of Manin’s Conjecture for Del Pezzo Surfaces

This paper surveys recent progress towards the Manin conjecture for (singular and non-singular) del Pezzo surfaces. To illustrate some of the techniques available, an upper bound of the expected order of magnitude is established for a singular del Pezzo surface of degree four.
