Abstract:In this paper, we prove some fixed point theorems for-monotone maps on partially ordered S-metric spaces. Our results generalize fixed point theorems in [1] and [7] for maps on metric spaces to the structure of S-metric spaces. Also, we give examples to demonstrate the validity of the results.
“…Sedghi, Shobe and Aliouche [19] asserted that S-metric space is a generalization of G-metric space. But, very recently Dung, Hieu and Radojevic [8] have verified by example (Example 2.1 and Example 2.2) that S-metric space is not a generalization of G-metric space or vice versa. Therefore, the classes of Gmetric spaces and S-metric spaces are different.…”

“…Therefore, the classes of Gmetric spaces and S-metric spaces are different. Recent papers dealing with fixed point theorems for mappings satisfying certain contractive conditions on S-metric spaces can be referred in [1,2,8,12,15,16,20]. Now we provide some preliminaries and basic definitions which we use throughout this paper.…”

“…Lemma 1.2. [8] Let (X, S) be an S-metric space. Then (i ) S(x, x, z) ≤ 2S(x, x, y) + S(y, y, z) and (ii ) S(x, x, z) ≤ 2S(x, x, y) + S(z, z, y).…”
In this paper, we introduce generalized (alpha, psi,phi)-contractive maps and provethe existence and uniqueness of xed points in complete S-metric spaces. We alsoprove that these maps satisfy property (P). We discuss the importance of study of the existence of xed points in S-metric space rather than in the setting of metric space.The results presented in this paper extends several well known comparable results in metric and G-metric spaces. We provide example in support of our result.

“…Recently, many authors studied the existence of fixed points of monotone nonexpansive mappings defined on partially ordered Banach spaces (see for example [10][11][12][13][14][15]). Recall that a self mapping T on X is said to be monotone nonexpansive if T is monotone and Tx − Ty ≤ x − y , for every comparable elements x and y.…”
In this paper, we give sufficient conditions to ensure the existence of the best proximity point of monotone relatively nonexpansive mappings defined on partially ordered Banach spaces. An example is given to illustrate our results.
