The number of conjugacy classes of elements of the Cremona group of some given finite order
Jérémy Blanc
This note presents the study of the conjugacy classes of elements of some given finite order n in the Cremona group of the plane. In particular, it is shown that the number of conj…

Finite abelian subgroups of the Cremona group of the plane
Jérémy Blanc
This work presents the conjugacy classes of finite abelian subgroups of the Cremona group of the plane. Using a well-known theory, this problem amounts to the study of automorphism…

Conjugacy classes of affine automorphisms of K^n and linear automorphisms of P^n in the Cremona groups
Jérémy Blanc
We describe the conjugacy classes of affine automorphisms in the group $Aut(n,\K)$ (respectively $Bir(\K^n)$) of automorphisms (respectively of birational maps) of $\K^n$. From thi…
