Constructing abelian extensions with prescribed norms
Christopher Frei, Rodolphe Richard
Given a number field , a finite abelian group and finitely many elements , we construct abelian extensions with Galois group that realise all…
Homogeneous Dynamics and Unlikely Intersections
R. Richard, A. Yafaev, T. Zamojski
This is a preliminary version of a monograph on homogeneous dynamics and application to some problems of unlikely intersections in Shimura varieties. It consists of four articles,…
A mod p variant of the André-Oort conjecture
Bas Edixhoven, Rodolphe Richard
We state and prove a variant of the André-Oort conjecture for the product of 2 modular curves in positive characteristic, assuming GRH for quadratic fields.
Inner Galois Equidistribution in S-Hecke orbits
Rodolphe Richard, Andrei Yafaev
We obtain results on the so-called Andre-Pink-Zannier conjecture which is a special case of a the Zilber-Pink conjecture on unlikely intersections in Shimura varieties. Our methods…
Limit distribution of Translated pieces of possibly irrational leaves in S-arithmetic homogeneous spaces
Rodolphe Richard, Thomas Zamojski
The purpose of this article is to describe and characterize the limit distributions of translates of a bounded open "piece of orbit" of a reductive subgroup on a space of S-arithme…
