Aggregation of fuzzy graphs.
Talavera, Francisco Javier; Bejines-López, Carlos; Ardanza Trevijano, Sergio; Elorza, Jorge (Elsevier, 2024-06-26)Our study is centered on the aggregation of fuzzy graphs, looking for conditions under which the aggregation process yields another fuzzy graph. We conduct an in-depth analysis of the preservation of several important ... -
Aggregation of fuzzy subgroups.
Bejines-López, Carlos; Chasco Ugarte, María Jesús; Elorza, Jorge (Elsevier, 2020-06-02)Given an aggregation function, and two fuzzy subgroups of a group, this study investigates whether the aggregation of them is also a fuzzy subgroup. It is proven that if the cardinal of the group is a prime power, then it ... -
Aggregation of fuzzy vector spaces.
Bejines-López, Carlos (Institute of Information Theory and Automation, 2023)This paper contributes to the ongoing investigation of aggregating algebraic structures, with a particular focus on the aggregation of fuzzy vector spaces. The article is structured into three distinct parts, each addressing ... -
Aggregation of indistinguishability operators.
Bejines-López, Carlos; Ardanza Trevijano, Sergio; Chasco Ugarte, María Jesús; Elorza, Jorge (Elsevier, 2021-05-04)The paper studies the aggregation of pairs of T-indistinguishability operators. More concretely we address the question whether is a T-indistinguishability operator if are T-indistinguishability operators. The answer ... -

Analysis of Fuzzy Vector Spaces as an Algebraic Framework for Flag Codes
Bejines-López, Carlos; Ojeda Hernández, Manuel; López-Rodríguez, Domingo (MDPI, 2024)Flag codes are a recent network coding strategy based on linear algebra. Fuzzy vector subspaces extend the notions of classical linear algebra. They can be seen as abstractions of flags to the point that several fuzzy ... -
Counting semicopulas on finite structures
Bejines-López, Carlos; Ojeda Hernández, Manuel (Elsevier, 2022)Semicopulas are the operators chosen to model conjunction in the fuzzy/many-valued logics. In fact, a special kind of semicopula, called t-norm, is widely used in many applications of logic to engineering, computer science ... -
Estudio de operadores discretos definidos sobre cadenas finitas.
En la lógica clásica, los predicados son binarios y toman valores de verdad de 0 o 1, que se corresponden con falso y verdadero, respectivamente. Sin embargo, en la mayoría de las veces, el razonamiento humano y muchos ... -
On Self-Aggregations of Min-Subgroups.
Bejines-López, Carlos; Ardanza Trevijano, Sergio; Elorza, Jorge (MDPI, 2021-08-19)Preservation of structures under aggregation functions is an active area of research with applications in many fields. Among such structures, min-subgroups play an important role, for instance, in mathematical morphology, ... -
Preserving fuzzy subgroups and indistinguishability operators
Bejines-López, Carlos; Chasco Ugarte, María Jesús; Elorza, Jorge; Recasens, Jordi (Elsevier, 2018)In this paper we study the class of all fuzzy subgroups defined with respect to a given t-norm on a fixed group. We find necessary and sufficient conditions over two t-norms to guarantee that the class of all fuzzy subgroups ... -
T-norms and t-conorms on a family of lattices
Bejines-López, Carlos (Elsevier, 2021)This paper provides a complete classification of all t-norms on a family of lattices in terms of t-norms on discrete chains. Moreover, the cardinal of some classes on discrete chains is computed. Therefore, the number of ... -
The Fibonacci sequence in the description of maximal discrete Archimedean t-norms.
Bejines-López, Carlos; Navara, Mirko (Elsevier, 2022-09-19)There are many arguments for counting with more than two “truth values”; this allows to imitate human reasoning of facts which are not binary. For theoretical reasons, it is natural to use the whole real interval as the ... -
The number of t-norms on some special lattices
Bejines-López, Carlos; Chasco Ugarte, María Jesús; Elorza, Jorge; Janis, Vladimir; Brutenicova, Michaela (Elsevier, 2020)We estimate the number of triangular norms on some classes of finite lattices. One of them is obtained from two chains by identifying their zero elements, unit elements and an atom. Another one is the set of the dual ...
