Résume
The Zilber-Pink conjecture predicts that a family of abelian surfaces over a one-dimensional base, with generic endomorphism ring ℤ, contains at most finitely many fibres with quaternionic multiplication. I will discuss a partial proof of this conjecture (joint with Christopher Daw). The main ingredients are new quantitative results in the reduction theory of algebraic groups and a height bound due to André.
