Description
Let
be a metric space endowed with a graph
such that the set
of vertices of
coincides with
. We define the notion of
-Zamfirescu maps and obtain a fixed point theorem for such mappings. This extends and subsumes many recent results which were obtained for mappings on metric spaces endowed with a graph and for cyclic operators.
