• openAccess   Endograph Metric and a Version of the Arzelà–Ascoli Theorem for Fuzzy Sets 

      Font, Juan J.; Macario, Sergio; Sanchis, Manuel MDPI (2023)
      In this paper, we provide several Arzelà–Ascoli-type results on the space of all continuous functions from a Tychonoff space X into the fuzzy sets of Rn , (FUSCB(Rn),Hend) , which are upper semi-continuous and have bounded ...
    • openAccess   Transitivity in Fuzzy Hyperspaces 

      Jardón, Daniel; Sánchez, Iván; Sanchis, Manuel MDPI (2020)
      Given a metric space (X, d), we deal with a classical problem in the theory of hyperspaces: how some important dynamical properties (namely, weakly mixing, transitivity and point-transitivity) between a discrete dynamical ...
