• openAccess   Sequentially compact subsets and monotone functions: An application to fuzzy theory 

      Font, Juan J.; Sanchis López, Manuel Elsevier (2015-09)
      Let (X,<,τO) be a first countable compact linearly ordered topological space. If (Y,D) is a uniform sequentially compact linearly ordered space with weight less than the splitting number s, then we characterize the ...
    • 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 ...
