Summary.
Using a fixed point method we investigate the existence of Lipschitzian solutions of the iterative functional equation¶¶\( \sum\limits_{i=1}^{\infty} \alpha_{i} f^{i}(x) = F(x)\ {\rm for}\ x \in \mathbb{B}, \)¶¶ where \( \mathbb{B} \) is a compact convex subset of \( \mathbb{R}^N \), and \( F : \mathbb{B} \to \mathbb{B} \) is a given Lipschitz function.
