Résumé :
Titre de la conférence : Some birational news (using tools from geometric group theory)The Oda conjecture states that every two birational toric varieties have a common iterated blowup. I will present the recent proof of the rational/weighted version of this conjecture, providing a constructive algorithm that reaches a common blowup using tricks I learned long ago to understand CAT(0) spaces. If time permits, I will also discuss relations to the solution of the semistable reduction conjecture. Joint work with Igor Pak.
