+ \begin{theorem}
+ \label{t:chaos des general}
+ The general chaotic iterations defined by
+ \begin{equation}
+ x_i^n=\left\{
+ \begin{array}{ll}
+ x_i^{n-1} & \text{ if } i \notin \mathcal{S}^n \\
+ \left(f(x^{n-1})\right)_{S^n} & \text{ if }i \in \mathcal{S}^n.
+ \end{array}\right.
+ \label{general CIs}

+satisfy
+ the Devaney's property of chaos.
