Binary relations coming from solutions of functional equations: orderings and fuzzy subsets
Campión Arrastia, María Jesús
; Miguel Turullols, Laura de ; García Catalán, Olga Raquel ; Induráin Eraso, Esteban ; Abrísqueta Usaola, Francisco Javier (World Scientific Publishing Company, 2017)
Artículo / Artikulua 
We analyze the main properties of binary relations, defined on a nonempty set, that arise in a natural way when dealing with real-valued functions that satisfy certain classical functional equations on two variables. We ... -
Comparison meaningful operators and ordinal invariant preferences
Candeal, Juan Carlos; Induráin Eraso, Esteban (Elsevier, 2015)
Artículo / Artikulua
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 ... -
Construction of admissible linear orders for interval-valued Atanassov intuitionistic fuzzy sets with an application to decision making
Miguel Turullols, Laura de ; Bustince Sola, Humberto ; Fernández Fernández, Francisco Javier ; Induráin Eraso, Esteban ; Kolesárová, Anna; Mesiar, Radko (Elsevier, 2015)
Artículo / Artikulua
In this work we introduce a method for constructing linear orders between pairs of intervals by using aggregation functions. We adapt this method to the case of interval-valued Atanassov intuitionistic fuzzy sets and we ... -
On the structure of acyclic binary relations
Rodríguez Alcantud, José Carlos; Campión Arrastia, María Jesús ; Candeal, Juan Carlos; García Catalán, Olga Raquel ; Induráin Eraso, Esteban (Springer, 2018)
Artículo / Artikulua
We investigate the structure of acyclic binary relations from different points of view. On the one hand, given a nonempty set we study real-valued bivariate maps that satisfy suitable functional equations, in a way that ... -
Pointwise aggregation of maps: its structural functional equation and some applications to social choice theory
Miguel Turullols, Laura de ; Campión Arrastia, María Jesús ; Candeal, Juan Carlos; Induráin Eraso, Esteban ; Paternain Dallo, Daniel (Elsevier, 2017)
Artículo / Artikulua
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 ; Candeal, Juan Carlos; Induráin Eraso, Esteban (The Korean Mathematical Society, 2009)
Artículo / Artikulua
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. -
Weightable quasi-metrics related to fuzzy sets
Campión Arrastia, María Jesús ; García Catalán, Olga Raquel ; Induráin Eraso, Esteban ; Valero, Óscar (Hacettepe University (Turquía), 2018)
Artículo / Artikulua
We show that the definition of a fuzzy set is directly related to the existence of a weightable quasi-metric on a universe. This relationship is also explored in terms of functional equations coming either from the membership ...
