    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. ...
