    Characterizations of partial metric completeness in terms of weakly contractive mappings having fixed point 
    Altun, Ishak; Romaguera Bonilla, Salvador (University of Belgrade and Academic Mind, 2012)
    We characterize both complete and 0-complete partial metri c spaces in terms of weakly contractive mappings having a fixed point. Our resu lts extend a well-known characterization of metric completeness due ...

    Improved F-contraction of rational type on partial metric spaces 
    Nazam, Muhammad; Arshad, Muhammad; Abbas, Mujahid (Universitat Politècnica de València, 2017-10-02)
    [EN] Following the approach of $F$- contraction introduced by Wardowski \cite{DW}, in this paper, we introduce improved $F$-contraction of rational type in the framework of partial metric spaces and used it to obtain a ...

    On Banach fixed point theorems for partial metric spaces 
    Valero, Oscar (Universitat Politècnica de València, 2005-10-01)
    [EN] In this paper we prove several generalizations of the Banach fixed point theorem for partial metric spaces (in the sense of O’Neill) given in, obtaining as a particular case of our results the Banach fixed point theorem ...

    Partial metrizability in value quantales 
    Kopperman, Ralph D.; Matthews, S.; Pajoohesh, H. (Universitat Politècnica de València, 2004-04-01)
    [EN] Partial metrics are metrics except that the distance from a point to itself need not be 0. These are useful in modelling partially defined information, which often appears in computer science. We generalize this notion ...

    T_0 functional Alexandroff topologies are partial metrizable 
    Pajoohesh, Homeira (Universitat Politècnica de València, 2024-10-01)
    [EN] If f : X → X is a function, the associated functional Alexandroff topology on X is the topology whose closed sets are {A ⊆ X : f(A) ⊆ A}. We prove that every functional Alexandroff topology is pseudopartial metrizable ...

    The canonical partial metric and the uniform convexity on normed spaces 
    Oltra, S.; Romaguera, Salvador; Sánchez-Pérez, E.A. (Universitat Politècnica de València, 2005-10-01)
    [EN] In this paper we introduce the notion of canonical partial metric associated to a norm to study geometric properties of normed spaces. In particular, we characterize strict convexity and uniform convexity of normed ...

    The local triangle axiom in topology and domain theory 
    Waszkiewicz, Pawel (Universitat Politècnica de València, 2003-04-01)
    [EN] We introduce a general notion of distance in weakly separated topological spaces. Our approach differs from existing ones since we do not assume the reflexivity axiom in general. We demonstrate that our partial ...
