Titre Tropical obstructions to stable rationality
Horaire15:45 à 17:00
RésumeIn joint work with Evgeny Shinder, we have attached to every "sufficiently nice" degeneration of algebraic varieties an obstruction to the stable rationality of a very general fiber. I will explain how tropical geometry can be used to construct such degenerations, and give some applications to rationality problems. This is joint work with John Christian Ottem.
