RT journal article T1 Characterizing reducts in multi-adjoint concept lattices A1 Cornejo Piñero, María Eugenia A1 Medina Moreno, Jesús A1 Ramírez Poussa, Eloísa A2 Matemáticas K1 Formal concept analysis; Reducts; Attribute reduction K1 Formal concept analysis K1 Reducts K1 Attribute reduction AB The construction of reducts, that is, minimal sets of attributes containing the main in- formation of a database, is a fundamental task in different frameworks, such as in For- mal Concept Analysis (FCA) and Rough Set Theory (RST). This paper will be focused on a general fuzzy extension of FCA, called multi-adjoint concept lattice, and we present a study about the attributes generating meet-irreducible elements and on the reducts in this framework. From this study, we introduce interesting results on the cardinality of reducts and the consequences in the classical case.
