RT Journal Article T1 Kitainik axioms do not characterize the class of inclusion measures based on contrapositive fuzzy implications A1 Madrid-Labrador, Nicolás Miguel A1 Cornelis, Chris K1 Matemáticas difusas AB In this short communication, we refute the conjecture by Fodor and Yager from [5] that the class of inclusion measures proposed by Kitainik coincides with that of inclusion measures based on contrapositive fuzzy implications. In particular, we show that the conjecture only holds when the considered universe of discourse is finite.
