    A Characterization of Strong Completeness in Fuzzy Metric Spaces 
    Gregori Gregori, Valentín; Miñana, Juan-José; Roig, Bernardino; Sapena Piera, Almanzor (MDPI AG, 2020-06)
    [EN] Here, we deal with the concept of fuzzy metric space(X,M,*), due to George and Veeramani. Based on the fuzzy diameter for a subset ofX, we introduce the notion of strong fuzzy diameter zero for a family of subsets. ...

    A construction of a fuzzy topology from a strong fuzzy metric 
    Grecova, Svetlana; Sostak, Alexander; Uljane, Ingrida (Universitat Politècnica de València, 2016-10-03)
    [EN] After the inception of the concept of a fuzzy metric by I. Kramosil and J. Michalek, and especially after its revision by A. George and G. Veeramani, the attention of many researches was attracted to the topology ...

    A contribution to the study of fuzzy metric spaces 
    Sapena Piera, Almanzor (Universitat Politècnica de València, 2001-04-01)
    [EN] We give some examples nad properties of fuzzy metric spaces, in the sense of George and Veramani, and characterize the To topological spaces which admit a compatible uniformity that has a countable transitive base, ...

    Cauchyness and convergence in fuzzy metric spaces 
    Gregori Gregori, Valentín; Miñana, Juan-José; Morillas, Samuel; Sapena Piera, Almanzor (Springer-Verlag, 2017)
    [EN] In this paper we survey some concepts of convergence and Cauchyness appeared separately in the context of fuzzy metric spaces in the sense of George and Veeramani. For each convergence (Cauchyness) concept we find a ...

    El concepto de métrica fuzzy a través del filtrado de imágenes digitales 
    Camarena, Joan-Gerard; Gregori, Valentín; Morillas, Samuel; Sapena, Almanzor (Universitat Politècnica de València, 2013-06-02)
    [EN] Fuzzy logic has been recently successfully used in several Engineering applications. In particular, fuzzy metrics have been applied to color image filtering improving, in many cases, classical filters results. In this ...

    Examples of fuzzy metrics and applications 
    Gregori Gregori, Valentín; Morillas, Samuel; Sapena Piera, Almanzor (Elsevier, 2011-05)
    In this paper we present new examples of fuzzy metrics in the sense of George and Veeramani. The examples have been classified attending to their construction and most of the well-known fuzzy metrics are particular cases ...

    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 ...

    On Principal Fuzzy Metric Spaces 
    Gregori Gregori, Valentín; Miñana, Juan-José; Morillas, Samuel; Sapena Piera, Almanzor (MDPI AG, 2022-08)
    [EN] In this paper, we deal with the notion of fuzzy metric space (X, M, *), or simply X, due to George and Veeramani. It is well known that such fuzzy metric spaces, in general, are not completable and also that there ...

    On the importance of metrics in practical applications 
    Camarena, Joan-Gerard; Morillas, Samuel; Cisneros, F.J. (Universitat Politècnica de València, 2011-06-05)
    [EN] Students motivation for learning mathematical concepts can be increased when showing the usefulness of these concepts in practical problems. One important mathematical concept is the concept of metric space and, more ...

    Peer group and fuzzy metric to remove noise in images using heterogeneous computing 
    Sanchez, Guadalupe; Vidal Gimeno, Vicente Emilio; Bataller Mascarell, Jordi (Springer Verlag (Germany), 2012)
    In this paper, we report a study on the parallelization of an algorithm for removing impulsive noise in images. The algorithm is based on the concept of peer group and fuzzy metric. We have developed implementations ...
