Abstract: Based on approach of BlancLamyZimmermann, I will explain how to find a non-trivial surjective homomorphism from the birational automorphism group of a rationally connected variety to an abelian group. After explaining main ideas, I will focus on the case of del Pezzo fibrations, extending results of the mentioned authors. This is a work in progress with Jeremy Blanc.
