A characterization of (U,N), RU, QL and D-implications derived from uninorms satisfying the law of importation
The law of importation is exhaustively studied for fuzzy implications derived from uninorms. All widely used classes of implications, that is (U,N), RU, QL and D-implications derived from most usual classes of uninorms are investigated. Along this study many new solutions of the law of importation appear different from those already known for implications derived from t-norms and t-conorms. (C) 2009 Elsevier B.V.
