Point counting for foliations over number fields

چکیده

We consider an algebraic variety and its foliation, both defined over a number field. prove upper bounds for the geometric complexity of intersection between leaf foliation subvariety complementary dimension (also field). Our depend polynomially on degrees, logarithmic heights, distance to certain \emph{locus unlikely intersections}. Under suitable conditions we show that this implies bound, polynomial in degree height, points transcendental sets using such foliations. deduce several results Diophantine geometry. i) Following Masser-Zannier, given pair sections $P,Q$ non-isotrivial family squares elliptic curves do not satisfy constant relation, whenever are simultaneously torsion their order is bounded effectively by degrees log-heights $P,Q$. In particular set simultaneous computable time. ii) Pila, $V\subset\mathbb{C}^n$ there (ineffective) log-height V, discriminants maximal special subvarieties. it follows Andr\'e-Oort powers modular curve decidable time (by algorithm depending universal, ineffective Siegel constant). iii) Schmidt, our counting result Galois-orbit lower bound type previously obtained transcendence methods David.

Genus 2 point counting over prime fields

For counting points of jacobians of genus 2 curves over a large prime field, the best known approach is essentially an extension of Schoof’s genus 1 algorithm. We propose various practical improvements to this method and illustrate them with a large scale computation: we counted hundreds of curves, until one was found that is suitable for cryptographic use, with a state-ofthe-art security level...

The point counting problem for curves over finite fields

The group law on elliptic curves is well-known and gives rise to elliptic curve cryptography systems which find application to government and industry today. However, the generalisation to higher genus requires the manipulation of divisor classes rather than points, and analogues of key genus 1 results have yet to be found. Nonetheless, effective computation within the group is possible, and te...

Lattice Point Counting and Height Bounds over Number Fields and Quaternion Algebras

An important problem in analytic and geometric combinatorics is estimating the number of lattice points in a compact convex set in a Euclidean space. Such estimates have numerous applications throughout mathematics. In this note, we exhibit applications of a particular estimate of this sort to several counting problems in number theory: counting integral points and units of bounded height over ...

Counting discriminants of number fields

For each transitive permutation group G on n letters with n ≤ 4, we give without proof results, conjectures, and numerical computations on discriminants of number fields L of degree n over Q such that the Galois group of the Galois closure of L is isomorphic to G.
