Décroissance exponentielle des corrélations pour un système dynamique réel induit d'un système en dimension 2

We study the discrete-time, real valued bounded process $\{X_n, n\in {\mathbb N} \}$ defined by a second order recurrence relation $X_{n+2} = φ(X_n,X_{n+1})$. We obtain the decay of correlations under analytical hypotheses on $φ$ (regularity, bounds on derivatives ...)
