    On Cyclic Generalized Weakly c-contractions on Partial Metric Spaces
    (Hindawi Ltd, 2013) Karapinar, Erdal; Rakocevic, Vladimir; Karapnar, Erdal
    We give new results of a cyclic generalized weakly C-contraction in partial metric space. The results of this paper extend, generalize, and improve some fixed point theorems in the literature.

    New Meir-Keeler Type Tripled Fixed-Point Theorems on Ordered Partial Metric Spaces
    (Hindawi Ltd, 2012) Aydi, Hassen; Karapinar, Erdal; Karapnar, 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.

    Θ-Metric Space: a Generalization
    (Hindawi Ltd, 2013) Khojasteh, Farshid; Karapınar, Erdal; Karapinar, Erdal; Radenovic, Stojan; Karapınar, Erdal; Karapnar, Erdal; Mathematics; Mathematics
    We introduce the notion of theta-metric as a generalization of a metric by replacing the triangle inequality with a more generalized inequality. We investigate the topology of the spaces induced by a theta-metric and present some essential properties of it. Further, we give characterization of well-known fixed point theorems, such as the Banach and Caristi types in the context of such spaces.

    Some Common Fixed Point Theorems in Partial Metric Spaces
    (Hindawi Ltd, 2011) Karapinar, Erdal; Yuksel, Ugur; Karapnar, Erdal
    Many problems in pure and applied mathematics reduce to a problem of common fixed point of some self-mapping operators which are defined on metric spaces. One of the generalizations of metric spaces is the partial metric space in which self-distance of points need not to be zero but the property of symmetric and modified version of triangle inequality is satisfied. In this paper, some well-known results on common fixed point are investigated and generalized to the class of partial metric spaces.

    Some Fixed Point Results for Multi-Valued Mappings in b-metric Spaces
    (Springeropen, 2014) Kutbi, Marwan Amin; Karapinar, Erdal; Ahmad, Jamshaid; Azam, Akbar; Karapnar, Erdal
    The aim of this paper is to establish some fixed point theorems for set-valued mappings in the context of b-metric spaces. The proposed theorems expand and generalize several well-known comparable results in the literature. An example is also given to support our main result.

    Coupled Coincidence Points in Partially Ordered Cone Metric Spaces With a c-distance
    (Hindawi Ltd, 2012) Shatanawi, Wasfi; Karapinar, Erdal; Aydi, Hassen; Karapnar, Erdal
    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.

    Tripled Fixed Point Results in Generalized Metric Spaces
    (Hindawi Ltd, 2012) Aydi, Hassen; Karapinar, Erdal; Shatanawi, Wasfi; Karapnar, Erdal
    We establish a tripled fixed point result for a mixed monotone mapping satisfying nonlinear contractions in ordered generalized metric spaces. Also, some examples are given to support our result.

    Some Fixed Point Results in gp-metric Spaces
    (Hindawi Ltd, 2012) Aydi, Hassen; Karapinar, Erdal; Salimi, Peyman; Karapnar, Erdal
    Following a recent paper of Zand and Nezhad (2011), we establish some fixed point results in GP-metric spaces. The presented theorems generalize and improve several existing results in the literature. Also, some examples are presented.
