    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, ...

    Completeness of Hutton [0,1]-quasi-uniformities induced by a crisp uniformity 
    Rodríguez López, Jesús; Romaguera Bonilla, Salvador; Sanchis, M. (2019)
    [EN] In [25], Katsaras introduced a method for constructing a Hutton [0, 1]-quasi-uniformity from a crisp uniformity. In this paper we present other different methods for making this based mainly in the concept of a fuzzy ...

    Convergence of fuzzy sets with respect to the supremum metric 
    Pedraza Aguilera, Tatiana; Rodríguez López, Jesús; Romaguera Bonilla, Salvador (Elsevier, 2014-01-16)
    We characterize the convergence of fuzzy sets in the supremum metric given by the supremum of the Hausdorff distances of the alpha-cuts of the fuzzy sets. We do it by dividing this metric into its lower and upper ...

    Fuzzy uniform structures 
    Rodríguez López, Jesús (National Library of Serbia, 2017)
    [EN] The concept of fuzzy uniform structure was introduced in [7] as a fuzzy counterpart of the concept of gauge associated with a uniformity. In fact, the category of fuzzy uniform structures is isomorphic to that of ...

    Hyperspace of a fuzzy quasi-uniform space 
    Pedraza Aguilera, Tatiana; Rodríguez López, Jesús (University of Sistan and Baluchestan, 2020-04)
    [EN] The aim of this paper is to present a fuzzy counterpart method of constructing the Hausdorff quasi-uniformity of a crisp quasi-uniformity. This process, based on previous works due to Morsi [25] and Georgescu [9], ...

    Hyperspaces of a weightable quasi-metric space: Application to models in the theory of computation 
    Künzi, H.P.A.; Rodríguez López, Jesús; Romaguera Bonilla, Salvador (Elsevier, 2010)
    It is well known that both weightable quasi-metrics and the Hausdorff distance provide efficient tools in several areas of Computer Science. This fact suggests, in a natural way, the problem of when the upper and lower ...

    McShane-Whitney extensions for fuzzy Lipschitz maps 
    Jiménez Fernández, Eduardo; Rodríguez López, Jesús; Sánchez Pérez, Enrique Alfonso (Elsevier, 2021-02-28)
    [EN] We present a McShane-Whitney extension theorem for real-valued fuzzy Lipschitz maps defined between fuzzy metric spaces. Motivated by the potential applications of the obtained results, we generalize the mathematical ...

    New results on the aggregation of norms 
    Pedraza Aguilera, Tatiana; Rodríguez López, Jesús (MDPI AG, 2021-09)
    [EN] It is a natural question if a Cartesian product of objects produces an object of the same type. For example, it is well known that a countable Cartesian product of metrizable topological spaces is metrizable. Related ...
