The goal of this ongoing joint project with Emiliano Ambrosi is to prove the irrationality of some complex varieties by degenerating them in characteristic 2, where they acquire a structure of « wild » conic bundle.This is inspired by a classical work of Artin and Mumford which I will recall. Our main result is a crystalline version of it.
