Migrativity properties of 2-uninorms over semi-t-operators
summary:In this paper, we analyze and characterize all solutions about -migrativity properties of the five subclasses of 2-uninorms, i. e. , , , , , over semi-t-operators. We give the sufficient and necessary conditions that make these -migrativity equations hold for all possible combinations of 2-uninorms over semi-t-operators. The results obtained show that for , the -migrativity of over a semi-t-operator is closely related to the -section of or the ordinal sum representation of t-norm and t-conorm corresponding to . But for the other four categories, the -migrativity over a semi-t-operator is fully determined by the -section of
On the α-migrativity of t-norms and t-conorms over nullnorms and uninorms
In this paper the notions of \alpha-migrative triangular norms over a fixed nullnorm and a fixed uninorm are introduced and studied. All solutions of the migrativity equation for all possible combinations of uninorms and nullnorms are analyzed and characterized. Similar study is done for triangular conorms
