چکیده
This paper establishes the Manin conjecture for a certain non-split singular del Pezzo surface of degree four X ⊂ P 4. In fact, if U ⊂ X is the open subset formed by deleting the lines from X, and H is the usual projective height function on P 4 (Q), then the height zeta function P x∈U (Q) H(x) −s is analytically continued to the half-plane ℜe(s) > 17/20.

Vojta’s Conjecture Implies the Batyrev-manin Conjecture for K3 Surfaces
Vojta’s Conjectures are well known to imply a wide range of results, known and unknown, in arithmetic geometry. In this paper, we add to the list by proving that they imply that rational points tend to repel each other on algebraic varieties with nonnegative Kodaira dimension. We use this to deduce, from Vojta’s Conjectures, conjectures of Batyrev-Manin and Manin on the distribution of rational...
متن کاملGAUSS-MANIN CONNECTION AND t-ADIC GEOMETRY
Let k be a field of characteristic zero, denote by R the ring k[[t]] of formal power series over k, and by K the field k((t)) of Laurent series over k. The aim of this note is to show that the de Rham cohomology of any separated and smooth rigid K-variety X carries a natural formal meromorphic connection ∂X , which we call the Gauss-Manin connection. It relates to the classical Gauss-Manin conn...

This paper contains a proof of the Manin conjecture for the singular cubic surface S ⊂ P 3 that is defined by the equation x1x 2 2 + x2x 2 0 + x 3 3 = 0. In fact if U ⊂ S is the Zariski open subset obtained by deleting the unique line from S, and H is the usual exponential height on P 3 (Q), then the height zeta function x∈U (Q) H(x) −s is analytically continued to the half-plane ℜe(s) > 9/10. ...
متن کاملO-minimality and the André-Oort conjecture for C
We give an unconditional proof of the André-Oort conjecture for arbitrary products of modular curves. We establish two generalizations. The first includes the Manin-Mumford conjecture for arbitrary products of elliptic curves defined over Q as well as Lang’s conjecture for torsion points in powers of the multiplicative group. The second includes the Manin-Mumford conjecture for abelian varietie...
