چکیده
|
In this paper, by providing an example, i show that the condition which produced by radenovi´c and kadelburg in [generalized weak contractions in partially ordered metric spaces, comput. math. appl. 60 (2010) pp. 1776-1783] is not sufficient for uniqueness of the fixed point. furthermore, a new sufficient condition is introduced for the uniqueness of the fixed point. some suitable examples are furnished to demonstrate the validity of the hypotheses of my results.
