of a database, is a fundamental task in different frameworks, such as in Formal 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 …
