COMMON FIXED POINTS OF GENERALIZED COUPLED α*_ ψ_ CONTRACTIVE MULTI-VALUED MAPPINGS ON ORDERED METRIC SPACES

Recently B. Samet, C. Vetro and P. Vetro introduced the notion of α_ ψ_contractive type mappings. They have been establish some fixed point theorems for the mappings in complete metric spaces. In this paper, we introduce the notion of general- ized coupled α*_ ψ_contractive multi-valued mappings on ordered metric spaces and give a common fixed point result about fixed points of the multi-valued mappings. Also, we give a result about common fixed points of self-maps on a partially ordered set and on complete metric satisfy a contractive condition.
