In this work, we discuss the law of α-migrativity as applied to fuzzy implication functions in a meaningful way. A generalisation of this law leads us to pexider-type generalisations of the law of importation, viz., the generalised law of importation I(C(α,x),y) = I(x,J(α,y)) (GLI) and the generalised cross-law of importation I(C(α,x),y)=J(x,I(α,y)) (CLI), where C is a generalised conjunction. We firstly show that the satisfaction of law of importation by the pairs (C,I) and/or (C,J) does not necessarily lead to the satisfaction of (GLI). Hence, we study the conditions under which these three laws may be related. © 2018 IEEE.
