Common fixed point theorems for weakly isotone increasing mappings in ordered partial metric spaces

Abstract

Common fixed point theorems for T-weakly isotone increasing mappings satisfying a generalized contractive type condition under a continuous function φ : [0, + ∞) →[0, + ∞) with φ (t) < t for each t> 0 and φ (0)= 0 in complete ordered partial metric spaces are proved. To illustrate our results and to distinguish them from the existing ones, we equip the paper with examples. © 2011 Elsevier Ltd.
