    • closedAccess   Some questions about Zadeh's extension on metric spaces 

      Jardón, Daniel; Sánchez, Iván; Sanchis López, Manuel Elsevier (2018-10-29)
      For a continuous function f on a Hausdorff space X , we prove that [ ̂ f(u) ] α = f(u α ) for each u ∈ F (X) and α ∈[ 0 , 1 ] , where ̂ f is the Zadeh’s extension of f . By ...
    • closedAccess   Spaces splittable over the class of Eberlein and descriptive compact spaces 

      Jardón, Daniel; Sanchis López, Manuel Springer Milan (2018)
      We study splittability over some classes of compact spaces which are useful in functional analysis and general topology. Among other things we show that a scattered pseudocompact space splittable over the class of Eberlein ...
    • 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 ...
