Rational Points on Cubic Surfaces

Let k be an algebraic number eld and F (x0; x1; x2; x3) a non{singular cubic form with coeecients in k. Suppose that the pro-jective cubic k{surface X P 3 k given by F = 0 contains three coplanar lines deened over k, and let U (k) be the set of k{points on X which does not lie on any line on X. We show that the number of points in U (k), with height at most B, is OF;"(B 4=3+") for any " > 0.

Rational Points on Elliptic Surfaces

x.1. Elliptic Surfaces Deenition. An elliptic surface consists of a smooth (projective) surface E, a smooth (projective) curve C, and a morphism : E ?! C such that almost all bers E t = ?1 (t) are (smooth projective) curves of genus 1. In addition, we will generally assume that our elliptic surfaces come equipped with an identity section 0 : C ?! E which serves as the identity element of the gr...

Counting Rational Points on Cubic Hypersurfaces

Let X ⊂ P be a geometrically integral cubic hypersurface defined over Q, with singular locus of dimension 6 dimX − 4. Then the main result in this paper is a proof of the fact that X(Q) contains Oε,X(B ) points of height at most B.

Counting Rational Points on Cubic Hypersurfaces: Corrigendum

R0<b162R0 gcd(b1, N )1/2 R 0 (HP) . The second line is false and in fact one has M1 = 1 in Proposition 3. The author is very grateful to Professor Hongze Li for drawing his attention to this flaw. The error can be fixed by introducing an average over b1 into the statement of Proposition 3. This allows us to recover the main theorem in [1], and also [2, Lemma 11], via the following modification....

COUNTING POINTS ON CUBIC SURFACES II Sir

Let V be a non-singular surface defined over Q which is embedded in projective space P by means of anticanonical divisors, and let U be the open subset of V obtained by deleting the lines on V . For any point P in U(Q) denote by h(P ) the height of P . In this paper h will usually be the standard height h1(P ) = max(|x0|, . . . , |xn|) where P = (x0, . . . , xn) for integers xi with highest com...
