D\'ecroissance exponentielle des corr\'elations pour un syst\`eme   dynamique r\'eel induit d'un syst\`eme 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 $X_{n+2} = \varphi(X_n,X_{n+1})$. We obtain the decay of correlations under analytical hypotheses on $\varphi $ (regularity, bounds on derivatives ...)
