Fifty years of similarity relations: a survey of foundations and applications
Recasens Ferrés, Jorge (2021-11-18)
Article
Accés obertOn the occasion of the 50th anniversary of the publication of Zadeh's significant paper Similarity Relations and Fuzzy Orderings, an account of the development of similarity relations during this time will be given. Moreover, ... -
Finding close T-indistinguishability operators to a given proximity
Garmendia Salvador, Luis; Recasens Ferrés, Jorge (-, 2007)
Text en actes de congrés
Accés obertTwo ways to approximate a proximity relation R (i.e. a reflexive and symmetric fuzzy relation) by a T-transitive one where T is a continuous archimedean t-norm are given. The first one aggregates the transitive closure R ... -
Finite-valued indistinguishability operators
Mayor, Gaspar; Recasens Ferrés, Jorge (2011-10)
Article
Accés restringit per política de l'editorialFuzzy equality relations or indistinguishability operators generalize the concepts of crisp equality and equivalence relations in fuzzy systems where inaccuracy and uncertainty is dealt with. They generate fuzzy granularity ... -
Finitely valued indistinguishability operators
Mayor, Gaspar; Recasens Ferrés, Jorge (Springer Verlag, 2010)

Fixed points and generators of fuzzy relations
Jacas Moral, Juan; Recasens Ferrés, Jorge (1994-08)
Article
Accés restringit per política de l'editorialThe fixed points of a T-indistinguishability operator are characterized as its generators in the sense of the Representation Theorem of Valverde. The geometric description of the set of fixed points of a reflexive and ... -
Funciones de implicación borrosas basadas en potencias
Massenet, Sabastià; Recasens Ferrés, Jorge; Torrens, Joan (2016)
Text en actes de congrés
Accés obertLa introducción de nuevas familias de funciones de implicación borrosas es una necesidad para poder elegir aquella más adecuada para una aplicación concreta. En esta línea, en este trabajo se introduce un nuevo tipo de ... -
Fuzzy actions
Boixader Ibáñez, Dionís; Recasens Ferrés, Jorge (2017-01-01)
Article
Accés obertThis paper generalizes (fuzzifies) actions of a monoid or group on a set to deal with situations where imprecision and uncertainty are present. Fuzzy actions can handle the granularity of a set or even create it by defining ... -
Fuzzy Groups, Fuzzy Functions and Fuzzy Equivalence Relations
Demirci, M; Recasens Ferrés, Jorge (2004-06)
Article
Accés restringit per política de l'editorialTo each fuzzy subgroup a fuzzy equivalence relation is associated and it is proved that a fuzzy subgroup is normal if and only if the operation of the group is compatible with its associated fuzzy equivalence relation. In ... -
Fuzzy implication functions based on powers of continuous t-norms
Massanet, Sebastià; Recasens Ferrés, Jorge; Torrens, Joan (2017-04-01)
Article
Accés obertThe modification (relaxation or intensification) of the antecedent or the consequent in a fuzzy “If, Then” conditional is an important asset for an expert in order to agree with it. The usual method to modify fuzzy ... -
Fuzzy numbers and equality relations
Jacas Moral, Juan; Recasens Ferrés, Jorge (IEEE pub., 1993)
Text en actes de congrés
Accés restringit per política de l'editorialA general approach to the concept of fuzzy number associated to a generalized equality on the real line is given. As a result, the use of triangular and trapezoidal fuzzy numbers, among other types, is justified and a ... -
Fuzzy t-transitive relations: eigenvectors and generators
Jacas Moral, Juan; Recasens Ferrés, Jorge (1995-02)
Article
Accés restringit per política de l'editorialAfter some preliminaries, the set of generators of a generalized equality relation (T-indistinguishability operator) is studied. This set is identified with the set of the eigenvectors of the relation. The relation between ... -
Generating indistinguishability operators from prototypes
Hernández, E; Recasens Ferrés, Jorge (Wiley InterScience, 2002-11)
Article
Accés restringit per política de l'editorialGiven a T-indistinguishability operator E defined between some fuzzy subsets of a universe of discourse X, this paper studies three ways to generate an indistinguishability operator on X compatible with E inspired by the ... -
Generation and Characterization of Fuzzy T-preorders
Boixader Ibáñez, Dionís; Recasens Ferrés, Jorge (2015-05-28)
Article
Accés obertThis article studies T-preorders that can be generated in a natural way by a single fuzzy subset. These T-preorders are called one-dimensional and are of great importance, because every T-preorder can be generated by ... -
Hesitant fuzzy relations and their transitive closure
Garmendia Salvador, Luis; González del Campo, Ramón; Recasens Ferrés, Jorge (2016)
Text en actes de congrés
Accés obertHesitant fuzzy relations and some of their operations are defined. A first definition of T-transitive property and its closure is defined. -

Indistinguishability operators generated by fuzzy numbers
Jacas Moral, Juan; Recasens Ferrés, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2004)
Text en actes de congrés
Accés restringit per política de l'editorialA new way to generate indistinguishability operators coherent with the underlying ordering structure of the real Dine is given in the sense that this structure should be compatible with the betweenness relation generated ... -

Article
Accés restringit per política de l'editorialAn isomorphism f between two continuous Archimedean t-norms T and T′ transforms a T-indistinguishability operator E into a T′-indistinguishability operator f ∘ E and many interesting properties of E are transfered to f ∘ ... -
