Speech Title: Implicational Tonoid Fuzzy Logics
Abstract: We investigate implicational tonoid fuzzy logics. We have at least three reasons to do this. One is that the present author (with a colleague) have introduced implicational tonoid logics as logics combining two classes of generalized logics, one of which is the class of weakly implicative logics introduced by Cintula and the other of which is the class of gaggle logics introduced by Dunn. Another is that, while a fuzzy version of weakly implicative logics has been introduced as weakly implicative fuzzy logics, such a version of gaggle logics has not. The other is that we can consider a fuzzy version of implicational tonoid logics. For this purpose, we introduce implicational tonoid fuzzy logics. First, we recall implicational tonoid logics in general. We then extend these to implicational tonoid fuzzy logics.
