Rational points on a certain genus 2 curve

open access: yesComptes Rendus. Mathématique, 2023
We give a correct proof to the fact that all rational points on the curve \[ y^2=(x^2+1)(x^2+3)(x^2+7) \] are $\pm \infty $ and $(\pm 1,\,\pm 8)$. This corrects previous works of Cohen [3] and Duquesne [4, 5].

On rational points in CFT moduli spaces

open access: yesJournal of High Energy Physics, 2021
Motivated by the search for rational points in moduli spaces of two-dimensional conformal field theories, we investigate how points with enhanced symmetry algebras are distributed there.

Families of polynomials of every degree with no rational preperiodic points

open access: yesComptes Rendus. Mathématique, 2021
Let $K$ be a number field. Given a polynomial $f(x)\in K[x]$ of degree $d\ge 2$, it is conjectured that the number of preperiodic points of $f$ is bounded by a uniform bound that depends only on $d$ and $[K:\mathbb{Q}]$.

Heights on stacks and a generalized Batyrev–Manin–Malle conjecture

open access: yesForum of Mathematics, Sigma, 2023
We define a notion of height for rational points with respect to a vector bundle on a proper algebraic stack with finite diagonal over a global field, which generalizes the usual notion for rational points on projective varieties.

Density of rational points on isotrivial rational elliptic surfaces [PDF]

open access: yes, 2011
For a large class of isotrivial rational elliptic surfaces (with section), we show that the set of rational points is dense for the Zariski topology, by carefully studying variations of root numbers among the fibers of these surfaces.

Game interrupted: The rationality of considering the future [PDF]

open access: yesJudgment and Decision Making, 2013
The ``problem of points'', introduced by Paccioli in 1494 and solved by Pascal and Fermat 160 years later, inspired the modern concept of probability. Incidentally, the problem also shows that rational decision-making requires the consideration of future

Varieties with too many rational points [PDF]

open access: yes, 2016
We investigate Fano varieties defined over a number field that contain subvarieties whose number of rational points of bounded height is comparable to the total number on the variety.Comment: 23 ...

Counting rational points on quadric surfaces

open access: yesDiscrete Analysis, 2018
Counting rational points on quadric surfaces, Discrete Analysis 2018:15, 29 pp. A _quadric hypersurface_ of dimension $D$ is the zero set of a quadratic form $Q$ in $D+2$ variables. If $Q(x_1,\dots,x_{D+2})=0$, then $Q(\lambda x_1,\dots,\lambda x_{D+2})=
