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 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 ... -
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 ... -
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 ...
