Abstract
Recently, Heman Kumar Nashine and Bessem Samet [H.K. Nashine, B. Samet, Fixed point results for mappings satisfying (psi, phi)-weakly contractive condition in partially ordered metric spaces, Nonlinear Anal. 74 (2011) 2201-2209] studied some coincidence fixed point and common fixed point theorems for two mappings satisfying (psi, phi)-weakly contractive condition in an ordered complete metric space. In the present paper, we study some coincidence fixed point and common fixed point theorems for three mappings S, T and R satisfying (psi, phi)-weakly contractive condition in an ordered complete metric space, where the mappings S and T are assumed to be weakly increasing with respect to R. Our results generalize several well-known results in the literature. (C) 2011 Elsevier Ltd. All rights reserved.
