COUPLED FIXED POINT THEOREMS FOR MIXED G-MONOTONE MAPPINGS IN PARTIALLY ORDERED METRIC SPACES VIA NEW FUNCTIONS
In this paper, we prove some coupled coincidence point results
for mixed g-monotone mappings in partially ordered metric spaces via new functions. The main results of this paper are generalizations of the main results of Luong and Thuan [ N.V. Luong, N.X. Thuan, Coupled fixed points in partially ordered metric spaces and application, Nonlinear Anal. 74 (2011) 983992].
