The canonical projection associated with certain possibly infinite generalized iterated function systems as a fixed point

In this paper, influenced by the ideas from Mihail (Fixed Point Theory Appl 2015:15, 2015), we associate to every generalized iterated function system \(\mathcal {F}\) (of order m) an operator \(H_{\mathcal {F}}:\mathcal {C} ^{m}\rightarrow \mathcal {C}\), where \(\mathcal {C}\) stands for the space of continuous functions from the shift space on the metric space corresponding to the system. We provide sufficient conditions (on the constitutive functions of \(\mathcal {F}\)) for the operator \(H_{\mathcal {F}}\) to be continuous, contraction, \(\varphi \)-contraction, Meir–Keeler or contractive. We also give sufficient condition under which \(H_{\mathcal {F}}\) has a unique fixed point \(\pi _{0}\). Moreover, we prove that, under these circumstances, the closure of the imagine of \(\pi _{0}\) is the attractor of \(\mathcal {F}\) and that \(\pi _{0}\) is the canonical projection associated with \(\mathcal {F}\). In this way we give a partial answer to the open problem raised on the last paragraph of the above-mentioned Mihail’s paper.
