It is well known that of all the extensions of the Banach-Caccioppoli Contraction Principle, the most general result was established by Ciric in 1974. In this paper, we will present some results related to Ciric type operator in complete metric spaces. Existence and uniqueness are re-called and several stability properties (data dependence and Ostrowski stability property) are proved. Using the retraction-displacement condition, we will establish the well-posedness and the Ulam-Hyers stability property of the fixed point equation x = f(x).
