Dynamics of a family of polynomial automorphisms of $C^{3}$ , a phase transition

Julie Déserti, Martin Leguil

The polynomial automorphisms of the affine plane have been studied a lot: if $f$ is such an automorphism, then either $f$ preserves a rational fibration, has an uncountable central…

Degree growth of polynomial automorphisms and birational maps: some examples

Julie Déserti

We provide the existence of new degree growths in the context of polynomial automorphisms of $C^{k}$ : if $k$ is an integer $\geq 3$ , then for any $\ell\leq \left[\frac{k-1}{…

Some properties of the group of birational maps generated by the automorphisms of $P_{C}^{n}$ and the standard involution

Julie Déserti

We give some properties of the subgroup $G_{n} (C)$ of the group of birational self-maps of $P_{C}^{n}$ generated by the standard involution and the group of au…

Nœther decomposition for birational maps

Julie Déserti

Let $ϕ$ be a birational map of the complex projective plane. We know that $ϕ$ can be written as a composition of automorphisms of $P_{C}^{2}$ and the standard quadrat…

Action of the Cremona group on foliations on $P_{C}^{2}$ : some curious facts

Dominique Cerveau, Julie Déserti

The Cremona group of birational transformations of $P_{C}^{2}$ acts on the space $F (2)$ of holomorphic foliations on the complex projective plane. Since this…

Representations of some lattices into the group of analytic diffeomorphisms of the sphere $S^{2}$

Julie Déserti

In \cite{Ghys} it is proved that any morphism from a subgroup of finite index of $SL (n, Z)$ to the group of analytic diffeomorphisms of $S^{2}$ has a finite…
