Participation IJCRS 2026
Intl Joint Conference of Rough Sets (IJCRS), May 25-28 2026, Cádiz, Spain
We participated with a communication, the organisation of a special session, and the presentation of a tutorial. The communication, with the title On a fuzzy inference system based on the notion of f -inclusion, was presented by Nicolás Madrid.
In the talk, the theoretical background of this type of FIS was recalled, together with a new result that asserts that the proposed system can be used for universal approximation of continuous functions.
In addition, Manuel Ojeda-Hernández participated in the organization of a Workshop on Conceptual structures and set approximations: A dialogue between Formal Concept Analysis and Rough Sets, together with co-organizers David Lobo and Dominika Kotlárova.
The tutorial fcaR: FCA for Knowledge Extraction in Real-World Environments was organised by Domingo López-Rodríguez and Ángel Mora, who was in charge of the presentation.
Last but not least, we had plenty of time to discuss scientific issues and potential collaboration with other colleagues. See below our table in the joint dinner together with Chris Cornelis (and Tanya), Davide Ciucci, Didier Dubois (and Genevieve), Salvatore Greco, Jesús Medina, Roberto Aragón, Maru Cornejo, Dominik Ślęzak and Yiyu Yao.

ABSTRACT This work extends our research on fuzzy relational Galois connections, previously established in the context of complete Heyting algebras, to the broader framework of arbitrary residuated lattices. In this context, we study the properties of fuzzy closure relations and fuzzy closure systems, and the relationship with fuzzy relational Galois connections. The main result of the paper is the generalization of the necessary and sufficient conditions for the existence of a right adjoint for a fuzzy relation linking a fuzzy transitive directed graph to an unstructured set.
