Séminaire Teich

Ce vendredi 7 mai à 11h nous aurons un Teich !
Dierk Schleicher nous parlera de ses résultats récents en collaboration avec Sergey Shemyakov, doctorant ici à AMU, sur la théorie de Thurston ancienne et nouvelle. Dierk sera là en présence mais nous mettrons aussi une vidéo pour ceux et celles qui veulent se joindre à distance.
Mode hybride ON.
Thurston theory old and new: decomposition of 3-manifolds and of surface automorphisms, and a new theorem in transcendental dynamics
We start by a panorama of closely related theorems by Thurston on geometrization of 3-manifolds, classification of surface automorphisms, and characterization of rational maps. These theorems are well known but often stated rather separately. We try to present them in a coherent way that highlights their close relations.
In the second part we will present a new theorem, in joint work with Sergey Shemyakov (AMU), that extends Thurston’s rational map theorem to a large class of transcendental functions; this responds to a conjecture raised by John Hubbard in the 1980’s.
