Artículo / Artikulua
In this paper we analyze the notion of a finite mean from an axiomatic point of view. We discuss several axiomatic alternatives, with the aim of establishing a universal definition reconciling all of them and exploring ... -

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 ... -
Computing with uncertainty truth degrees: a convolution-based degrees
Miguel Turullols, Laura de (2017)
Tesis doctoral / Doktoretza tesia
La teoría de los conjuntos difusos puede contemplarse como un conjunto de herramientas matemáticas excepcionalmente adaptadas para trabajar con información incompleta, falta de nitidez e incertidumbre no aleatoria. De ... -
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 ... -
Decomposition and arrow-like aggregation of fuzzy preferences
Raventós Pujol, Armajac ; Campión Arrastia, María Jesús ; Induráin Eraso, Esteban (MDPI, 2020)
Artículo / Artikulua
We analyze the concept of a fuzzy preference on a set of alternatives, and how it can be decomposed in a triplet of new fuzzy binary relations that represent strict preference, weak preference and indifference. In this ... -
Geometrical aggregation of finite fuzzy sets
Campión Arrastia, María Jesús ; García Catalán, Olga Raquel ; Induráin Eraso, Esteban ; Lizasoain Iriso, María Inmaculada ; Raventós Pujol, Armajac ; Valero, Óscar (Elsevier, 2018)
Artículo / Artikulua
A fuzzy set on a finite universe can be interpreted as a vector in a unit cube. This gives rise to a huge variety of approaches in order to aggregate finite fuzzy sets or to modify a given one. We analyze several geometrical ... -
Multidistances and inequality measures on abstract sets: an axiomatic approach
Campión Arrastia, María Jesús ; Díaz, Irene; Induráin Eraso, Esteban ; Martín, Javier; Mayor, Gaspar; Montes Rodríguez, Susana; Raventós Pujol, Armajac (Elsevier, 2021)
Artículo / Artikulua
Starting from the notion of a multidistance, we formalize, through a suitable system of axioms, the concept of an inequality measure defined on a nonempty set with no additional structure implemented a priori. Among ... -
New trends on the numerical representability of semiordered structures

(EUSFLAT, 2012)
Artículo / Artikulua
We introduce a survey, including the historical background, on di erent techniques that have recently been issued in the search for a characterization of the representability of semiordered structures, in the sense of ... -
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 ... -
Open questions in utility theory
