    • On completeness and direction in fuzzy relational systems 

      Burillo López, Pedro Upna; Fuentes González, Ramón Upna Orcid; González, L. (Universitat Politècnica de Catalunya, 1998)   Artículo / Artikulua  OpenAccess
      The concepts of bounded subset, complete subset and directed subset, which are well known in the context of partially ordered sets (X, ≤), are extended in order to become applicable, with coherence, in fuzzy relational ...
    • On contrast intensification operators and fuzzy equality relations 

      Burillo López, Pedro Upna; Fuentes González, Ramón Upna Orcid; González, L.; Marín Martínez, Ángel Upna (Universitat Politècnica de Catalunya, 2000)   Artículo / Artikulua  OpenAccess
      The class of contrast intensification operators is formally defined and its lattice structure studied. The effect of these operators in the referential classification derived from special kinds of fuzzy relations is also ...
    • Overtaker binary relations on complete completely distributive lattices related to the level sets of the L-fuzzy sets 

      Núñez, A.; Burillo López, Pedro Upna; Fuentes González, Ramón Upna Orcid; González, L. (Universitat Politècnica de Catalunya, 1994)   Artículo / Artikulua  OpenAccess
      The class of overtaker binary relations associated with the order in a lattice is defined and used to generalize the representations of L-fuzzy sets by means of level sets or fuzzy points.
