Linear actions of free groups
[Actions linéaires des groupes libres]
Annales de l'Institut Fourier, Tome 51 (2001) no. 1, pp. 131-150.

Dans cet article nous étudions les propriétés dynamiques des actions linéaires des groupes libres par l'action induite sur l'espace projectif. Ce point de vue nous permet de présenter des techniques du formalisme thermodynamique. En particulier, nous obtenons des estimations sur les croissances des orbites et leurs distributions limites sur l'espace projectif.

In this paper we study dynamical properties of linear actions by free groups via the induced action on projective space. This point of view allows us to introduce techniques from Thermodynamic Formalism. In particular, we obtain estimates on the growth of orbits and their limiting distribution on projective space.
