Ordinary isogeny graphs over $F_{p}$ : the inverse volcano problem

Henry Bambury, Francesco Campagna, Fabien Pazuki

We give a detailed presentation of $ℓ$ -isogeny graphs associated with ordinary elliptic curves defined over $F_{p}$ . We then focus on the following inverse problem: given…

Around the support problem for Hilbert class polynomials

Francesco Campagna, Gabriel Andreas Dill

Let $H_{D} (T)$ denote the Hilbert class polynomial of the imaginary quadratic order of discriminant $D$ . We study the rate of growth of the greatest common divisor of $H_{D} (a)$ and $H…

On singular moduli that are S-units

Francesco Campagna

Recently Yu. Bilu, P. Habegger and L. Kühne proved that no singular modulus can be a unit in the ring of algebraic integers. In this paper we study for which sets S of prime number…
