ABSTRACT
In this paper, we will present a study of the fixed point equation (where
is a generalized metric space in the sense that
and
is a graph contraction) by the following perspectives: existence, uniqueness, approximation, data dependence of the operator perturbation, well-posedness, and Ulam-Hyers stability. The non-self case is also discussed and some applications are given.
