Sphere packings, mostly in R^n, and beta-integers, are the objects considered in this thesis. They are indifferently described in the language of sphere packings or in...

We study the selfsimilarity and the Gibbs properties of several measures defined on the product space $\Omega_r:=\{0,1,\dots,\break r-1\}^{\mathbb N}$. This space can...

We consider the infinite sequences $(A_n)_{n\in\NN}$ of $2\times2$ matrices with nonnegative entries, where the $A_n$ are taken in a finite set of matrices. Given a...
