    A technique for fuzzifying metric spaces via metric preserving mappings 
    Gregori Gregori, Valentín; Miñana, Juan-José; Valero Sierra, Óscar (Elsevier, 2018)
    [EN] In this paper we develop a new technique for constructing fuzzy metric spaces, in the sense of George and Veeramani, from metric spaces and by means of the Lukasievicz t-norm. In particular such a technique is based ...

    Aggregation of fuzzy quasi-metrics 
    Pedraza Aguilera, Tatiana; Rodríguez López, Jesús; Valero, Óscar (Elsevier, 2021-12)
    [EN] In the last years fuzzy (quasi-)metrics and indistinguishability operators have been used as a mathematical tool in order to develop appropriate models useful in applied sciences as, for instance, image processing, ...

    Complete partial metric spaces have partially metrizable computational models 
    Romaguera Bonilla, Salvador; Tirado Peláez, Pedro; Valero Sierra, Óscar (Taylor & Francis Ltd, 2012)
    We show that the domain of formal balls of a complete partial metric space (X, p) can be endowed with a complete partial metric that extends p and induces the Scott topology. This result, that generalizes well-known ...

    Complexity spaces as quantitative domains of computation 
    Romaguera Bonilla, Salvador; Schellekens, M.P.; Valero Sierra, Óscar (Elsevier, 2011-04)
    We study domain theoretic properties of complexity spaces. Although the so-called complexity space is not a domain for the usual pointwise order, we show that, however, each pointed complexity space is an ¿-continuous ...

    Fuzzy Partial Metric Spaces and Fixed Point Theorems 
    Aygün, Halis; Güner, Elif; Miñana, Juan-José; Valero, Oscar (MDPI AG, 2022-09)
    [EN] Partial metrics constitute a generalization of classical metrics for which self-distance may not be zero. They were introduced by S.G. Matthews in 1994 in order to provide an adequate mathematical framework for the ...

    New results on the mathematical foundations of asymptotic complexity analysis of algorithms via complexity spaces 
    Romaguera Bonilla, Salvador; Tirado Peláez, Pedro; Valero Sierra, Óscar (Taylor & Francis Ltd, 2012)
    Schellekens [The Smyth completion: A common foundation for denotational semantics and complexity analysis, Electron. Notes Theor. Comput. Sci. 1 (1995), pp. 211-232.] introduced the theory of complexity (quasi-metric) ...

    On the domain of formal balls of the Sorgenfrey quasi-metric space 
    Romaguera Bonilla, Salvador; Schellekens, Michel; Tirado Peláez, Pedro; Valero Sierra, Óscar (Elsevier, 2016)
    [EN] We show that the poset of formal balls of the Sorgenfrey quasi-metric space is an omega-continuous domain, and deduce that it is also a computational model, in the sense of R.C. Flagg and R. Kopperman, for the Sorgenfrey ...

    Relaxed Indistinguishability Relations and Relaxed Metrics: The Aggregation Problem 
    González-Hedström, Juan-De-Dios; Miñana, Juan-José; Valero, Oscar (MDPI AG, 2022-09)
    [EN] The main purpose of this paper is to study the relationship between those functions that aggregate relaxed indistinguishability fuzzy relations with respect to a collection of t-norms and those functions that merge ...
