Sur les automorphismes du groupe de Cremona

[摘要] We prove that an automorphism of the group of birational transformations of the complex projective plane is the composition of an interior automorphism and an automorphism of the field $mathbb{C}$. The proof is based on a study of maximal abelian subgroups of the Cremona group.
