TRIPLED COINCIDENCE POINT THEOREMS FOR WEAK φ-CONTRACTIONS IN ORDERED PARTIAL METRIC SPACES

We prove some tripled coincidence and common fixed point results of mapping s satisfying a contraction type. These results extend the tripled coincidence and common fixed point theorems for g mixed monotone operators F : X3 → X obtained in [Fixed Point Theory Appl., Volume 2012, 2012:44], by Aydi, Karapinar and Postolache, to the class of partially ordered partial metric spaces.
