    New Meir-Keeler Type Tripled Fixed-Point Theorems on Ordered Partial Metric Spaces
    (Hindawi Ltd, 2012) Aydi, Hassen; Karapinar, Erdal
    In this paper, we prove some new Meir-Keeler type tripled fixed-point theorems on a partially ordered complete partial metric space. Also, as application, some results of integral type are given.

    Coupled Fixed Points for Meir-Keeler Contractions in Ordered Partial Metric Spaces
    (Hindawi Ltd, 2012) Abdeljawad, Thabet; Aydi, Hassen; Karapinar, Erdal
    In this paper, we prove the existence and uniqueness of a new Meir-Keeler type coupled fixed point theorem for two mappings F : X x X -> X and g : X -> X on a partially ordered partial metric space. We present an application to illustrate our obtained results. Further, we remark that the metric case of our results proved recently in Gordji et al. (2012) have gaps. Therefore, our results revise and generalize some of those presented in Gordji et al. (2012)

    A Generalized Meir-Keeler Contraction on Partial Metric Spaces
    (Hindawi Ltd, 2012) Aydi, Hassen; Karapinar, Erdal; Rezapour, Shahram
    We introduce a generalization of the Meir-Keeler-type contractions, referred to as generalized Meir-Keeler-type contractions, over partial metric spaces. Moreover, we show that every orbitally continuous generalized Meir-Keeler-type contraction has a fixed point on a 0-complete partial metric space.

    Coupled Coincidence Point and Coupled Fixed Point Theorems via Generalized Meir-Keeler Type Contractions
    (Hindawi Ltd, 2012) Aydi, Hassen; Karapinar, Erdal; Erhan, Inci M.
    We prove coupled coincidence point and coupled fixed point results of F : X x X -> X and g : X -> X involving Meir-Keeler type contractions on the class of partially ordered metric spaces. Our results generalize some recent results in the literature. Also, we give some illustrative examples and application.

    Fixed Point Theorems for Various Classes of Cyclic Mappings
    (Hindawi Ltd, 2012) Aydi, Hassen; Karapinar, Erdal; Samet, Bessem
    We introduce new classes of cyclic mappings and we study the existence and uniqueness of fixed points for such mappings. The presented theorems generalize and improve several existing results in the literature.

    Coupled Coincidence Points in Partially Ordered Cone Metric Spaces With a c-distance
    (Hindawi Ltd, 2012) Shatanawi, Wasfi; Karapinar, Erdal; Aydi, Hassen
    Cho et al. (2012) proved some coupled fixed point theorems in partially ordered cone metric spaces by using the concept of a c-distance in cone metric spaces. In this paper, we prove some coincidence point theorems in partially ordered cone metric spaces by using the notion of a c-distance. Our results generalize several well-known comparable results in the literature. Also, we introduce an example to support the usability of our results.

    Some Almost Generalized (ψ, Φ)-Contractions in g-metric Spaces
    (Hindawi Ltd, 2013) Aydi, Hassen; Amor, Sana Hadj; Karapinar, Erdal
    In this paper, we introduce some almost generalized (psi, phi)-contractions in the setting of G-metric spaces. We prove some fixed points results for such contractions. The presented theorems improve and extend some known results in the literature. An example is also presented.

    ,ψ)-meir-keeler Contraction Mappings in Generalized b-metric Spaces
    (Hindawi Ltd, 2018) Karapinar, Erdal; Czerwik, Stefan; Aydi, Hassen
    We present a fixed point theorem for generalized (alpha, Psi)-Meir-Keeler type contractions in the setting of generalized b-metric spaces. The presented results improve, generalize, and unify many existing famous results in the corresponding literature.

    Berinde-Type Generalized Contractions on Partial Metric Spaces
    (Hindawi Ltd, 2013) Aydi, Hassen; Amor, Sana Hadj; Karapinar, Erdal
    We consider generalized Berinde-type contractions in the context of partial metric spaces. Such contractions are also known as generalized almost contractions in the literature. In this paper, we extend, generalize, and enrich the results in this direction. Some examples are presented to illustrate our results.

    Existence of Solutions for a Periodic Boundary Value Problem Via Generalized Weakly Contractions
    (Hindawi Ltd, 2013) Moradi, Sirous; Karapinar, Erdal; Aydi, Hassen
    We discuss the existence of solutions for a periodic boundary value problem and for some polynomials. For this purpose, we present some fixed point theorems for weakly and generalized weakly contractive mappings in the setting of partially ordered complete metric spaces.
