Fixed point and common fixed point theorems on ordered cone metric spaces
and Applied Analysis 3 effectively larger than that of the ordinary conemetric spaces. That is, every cone metric space is a cone b-metric space, but the converse need not be true. The following examples show the above remarks. Example 7. Let X = {−1, 0, 1}, E = R, andP = {(x, y) : x ≥ 0, y ≥ 0}. Define d : X × X → P by d(x, y) = d(y, x) for all x, y ∈ X, d(x, x) = θ, x ∈ X, and d(−1, 0) = (3, ...
متن کاملCommon Fixed Point Theorems in Ordered Cone Metric Spaces
In this paper we extend some existing results and prove fixed point theorem on partially ordered cone metric spaces which satisfy certain weak contractive inequalities. In this consequence we have also given some illustrative examples.
متن کاملA common fixed point theorem on ordered metric spaces
A common fixed point result for weakly increasing mappings satisfying generalized contractive type of Zhang in ordered metric spaces are derived.
متن کاملFixed point theorems on generalized $c$-distance in ordered cone $b$-metric spaces
In this paper, we introduce a concept of a generalized $c$-distance in ordered cone $b$-metric spaces and, by using the concept, we prove some fixed point theorems in ordered cone $b$-metric spaces. Our results generalize the corresponding results obtained by Y. J. Cho, R. Saadati, Shenghua Wang (Y. J. Cho, R. Saadati, Shenghua Wang, Common fixed point heorems on generalized distance in ordere...
متن کاملCoupled Fixed Point Theorems in Partially Ordered Cone Metric Spaces
This paper is concerned with mixed monotone mappings in partially ordered cone metric spaces. We establish several fixed point theorems, which generalize and complement some known results. Especially, even in a partially ordered metric space, our main results are generalizations of the fixed point theorems due to Bhaskar and Lakshmikantham [T. Grana Bhaskar, V. Lakshmikantham, Fixed point theor...
