Ulam-Hyers stability for coupled fixed points of contractive type operators.

In this paper, we present existence, uniqueness and Ulam-Hyers stability results for the coupled fiixed points of a pair of contractive type singlevalued and respectively multivalued operators on complete metric spaces. The approach is based on Perov type fixed point theorem for contractions in spaces endowed with vector- valued metrics. [ABSTRACT FROM AUTHOR]
