Abstract

The purpose of this paper is to study fixed point theorems for a mapping satisfying the cyclical generalized contractive conditions in complete partial metric spaces. Our results generalize or improve many recent fixed point theorems in the literature.

Summary

Ai is called a cyclic representation of

The fixed theorems for an operator f : X → X defined on a metric space X with a cyclic representation of X with respect to f have appeared in the literature (see, e.g., [ – ]). ( ) there exists a continuous, non-decreasing function φ : [ , ∞) → [ , ∞) with φ(t) >. Theorem [ ] Let (X, d) be a complete metric space, m ∈ N, A , A , . The purpose of this paper is to study fixed point theorems for a mapping satisfying the cyclical generalized contractive conditions in complete partial metric spaces. We state a new notion of cyclic CW-contractions in partial metric spaces as follows.
