Abstract:

We study the decay of correlations for towers. Using Birkhoff's projective metrics, we obtain a rate of mixing of the form:

\begin{displaymath}c_n (f,g) \leq \text{\rm Ct} \alpha(n) \Vert f \Vert \, \Vert g \Vert_1\end{displaymath}

where $\alpha(n)$ goes to zero in a way related to the asymptotic mass of upper floors, $\Vert f\Vert$ is some Lipschitz norm and $\Vert g \Vert_1$ is some $L^1$ norm. The fact that the dependence on $g$ is given by an $L^1$ norm is useful to study asymptotic laws of successive entrance times.
