Generalised André-Pink-Zannier Conjecture for Shimura varieties of abelian type

Rodolphe Richard, Andrei Yafaev

In this paper, we prove the generalised André-Pink-Zannier conjecture (an important case of the Zilber-Pink conjecture) for all Shimura varieties of abelian type. Questions of thi…

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 al…

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…

Heights on 'Hybrid orbits' in Shimura varieties

Rodolphe Richard, Andrei Yafaev

We prove the 'hybrid conjecture' which is a common generalisation of the Andreé-Oort conjecture and the André-Pink-Zannier conjecture, in the case of Shimura varieties of abelian…

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.
