• #### A characterization for residuated implications on J [0, 1]. Application to the L-fuzzy concept theory. ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2005)
Article
Open Access
In this paper, a new characterization for the interval-valued residuated fuzzy implication operators is presented, with which it is possible to use them in a simple and efficient way, since the calculation of the values ...
• #### Concept lattices associated with L-Fuzzy W-contexts ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1996)
Article
Open Access
\begin{abstract} \noindent We generalize in this paper the $L$-Fuzzy concept theory we developed in a previous paper ([1]), using the composition of $L$-Fuzzy relations. This theory models knowledge acquisition ...
• #### The embedding if the formal concept analysis inte the L-fuzzy concept theory ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1998)
Article
Open Access
In this work, we study the relation between the concept lattice of Wille ([5], [6]) and the $L-Fuzzy$ concept lattice ([2]) developed by us. To do it, we have defined an application $g$ that associates to each concept ...
• #### The study of the L-fuzzy concept lattice ﻿

(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1994)
Article
Open Access
The L-Fuzzy concept theory that we have developed sets up classifications from the objects and attributes of a context through L-Fuzzy relations. This theory generalizes the formal concept theory of R. Wille. In this paper ...
