    • Comparison meaningful operators and ordinal invariant preferences 

      Candeal, Juan Carlos; Induráin Eraso, Esteban Upna (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      The existence of a continuous and order-preserving real-valued function, for the class of continuous and ordinal invariant total preorders, defined on the Banach space of all bounded real-valued functions, which are in ...
    • Pointwise aggregation of maps: its structural functional equation and some applications to social choice theory 

      Miguel Turullols, Laura de Upna; Campión Arrastia, María Jesús Upna; Candeal, Juan Carlos; Induráin Eraso, Esteban Upna; Paternain Dallo, Daniel Upna (Elsevier, 2017)   Artículo / Artikulua  OpenAccess
      We study a structural functional equation that is directly related to the pointwise aggregation of a finite number of maps from a given nonempty set into another. First we establish links between pointwise aggregation and ...
    • Semicontinuous planar total preorders on non-separable metric spaces 

      Campión Arrastia, María Jesús Upna; Candeal, Juan Carlos; Induráin Eraso, Esteban Upna (The Korean Mathematical Society, 2009)   Artículo / Artikulua  OpenAccess
      We prove that every non-separable connected metric space can be endowed with a total preorder that is order-isomorphic to a nonrepresentable subset of the lexicographic plane and semicontinuous with respect to the metric topology.
