We establish common fixed point theorems for weakly compatible generalized φcontractions. As applications, various common fixed point and best approximation results for Cq-commuting and compatible maps are derived. Our results unify, extend and complement various known results existing in the literature.

The purpose of this paper is to present some fixed point results for cyclic φ-contractions in a complete metric space endowed with a partial order.

for all x, y Î X, where : R+ ® R+ is a nondecreasing function such that lim n→∞ φ n(t) = 0 for all t > 0. In 1994, Matthews [4] introduced the notion of a partial metric space and obtained a generalization of Banach’s fixed point theorem for partial metric spaces. Recently, Altun et al. [5] (see also Altun and Sadarangani [6]) gave some generalized versions of the fixed point theorem of Matthew...
