    Fuzzy quasi-metric spaces 
    Gregori, Valentín; Romaguera, Salvador (Universitat Politècnica de València, 2004-04-01)
    [EN] We generalize the notions of fuzzy metric by Kramosil and Michalek, and by George and Veeramani to the quasi-metric setting.We show that every quasi-metric induces a fuzzy quasi-metric and ,conversely, every fuzzy ...

    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 ...

    Continuous functions with compact support 
    Acharyya, Sudip Kumar; Chattopadhyaya, K.C.; Ghosh, Partha Pratim (Universitat Politècnica de València, 2004-04-01)
    [EN] The main aim of this paper is to investigate a subring of the ring of continuous functions on a topological space X with values in a linearly ordered field F equipped with its order topology, namely the ring of ...

    A countably compact free Abelian group whose size has countable cofinality 
    Castro Pereira, I.; Tomita, A.H. (Universitat Politècnica de València, 2004-04-01)
    [EN] Based on some set-theoretical observations, compactness results are given for general hit-and-miss hyperspaces. Compactness here is sometimes viewed splitting into “k-Lindelöfness” and ”k-compactness” for cardinals ...

    Homeomorphisms of R and the Davey Space 
    Carter, Sheila; Craveiro de Carvalho, F.J. (Universitat Politècnica de València, 2004-04-01)
    [EN] Up to homeomorphism, there are 9 topologies on a three point set {a, b, c}. Among the resulting topological spaces we have the so called Davey space, where the only non-trivial open set is, let us say, {a}. This is ...
