    Fixed Point Theorem on Partial Metric Spaces Involving Rational Expressions
    (University of Miskolc, 2013) Karapinar,E.; Shatanawi,W.; Tas,K.
    We establish a fixed point theorem involving a rational expression in a complete partial metric space. Our result generalizes a well-known result in (usual) metric spaces. Also, we introduce an example to illustrate the usability of our result. © Miskolc University Press.

    A Note on Common Fixed Point Theorems in Partial Metric Spaces
    (University of Miskolc, 2011) Karapinar,E.
    In this manuscript, we consider the notion of generalized Sehgal contraction condition in a partial metric space. For the pair of two self mappings (S, T) which satisfies Sehgal contraction condition, we obtain a unique common fixed point. © 2011 Miskolc University Press.

    Weak ø-Contraction on partial metric spaces
    (2012) Karapinar,E.
    In this manuscript, the notion of weak ø-contraction is considered on partial metric space. It is shown that a self mapping T on a complete partial metric space X has a fixed point if they satisfied weak ø-contraction. © 2012 EUDOXUS PR20E6SS, LLC.

    Existence and uniqueness of a common fixed point on partial metric spaces
    (Pergamon-elsevier Science Ltd, 2011) Abdeljawad, T.; Karapinar, E.; Tas, K.
    In this work, a general form of the weak phi-contraction is considered on partial metric spaces, to get a common fixed point. It is shown that self-mappings S, T on a complete partial metric space X have a common fixed point if it is a generalized weak phi-contraction. (C) 2011 Elsevier Ltd. All rights reserved.

    Fixed Point Theorem for Cyclic Maps on Partial Metric Spaces
    (Natural Sciences Publishing Corp-nsp, 2012) Karapinar, E.; Erhan, I. M.; Ulus, A. Yildiz; Mathematics
    In this paper, a class of cyclic contractions on partial metric spaces is introduced. A fixed point theorem for cyclic contractions on partial metric spaces satisfying (psi, phi) contractive condition, and illustrative examples are given.

    On Ekeland's Variational Principle in Partial Metric Spaces
    (Natural Sciences Publishing Co., 2015) Aydi,H.; Karapinar,E.; Vetro,C.
    In this paper, lower semi-continuous functions are used to extend Ekeland's variational principle to the class of partial metric spaces. As consequences of our results, we obtain some fixed point theorems of Caristi and Clarke types. © 2015 NSP.

    Generalizations of Caristi Kirk's Theorem on Partial Metric Spaces
    (Springer international Publishing Ag, 2011) Karapinar, Erdal
    In this article, lower semi-continuous maps are used to generalize Cristi-Kirk's fixed point theorem on partial metric spaces. First, we prove such a type of fixed point theorem in compact partial metric spaces, and then generalize to complete partial metric spaces. Some more general results are also obtained in partial metric spaces. 2000 Mathematics Subject Classification 47H10,54H25

    Common Fixed Points for Generalized -Implicit Contractions in Partial Metric Spaces: Consequences and Application
    (Springer-verlag Italia Srl, 2015) Aydi, Hassen; Jellali, Manel; Karapinar, Erdal
    In this paper, we introduce the concept of generalized -admissible pair of mappings generalizing the definition of -admissible mappings presented by Samet et al. (Nonlinear Anal 75:2154-2165, 2012). Based on above, we define generalized -implicit contractions in the setting of partial metric spaces and we provide some common fixed point results for such contractions. We also derive some consequences and corollaries from our obtained results. An application and some examples are presented making effective the new concepts and results.
