摘要

In this paper, we investigate the migrativity of uninorms and nullnorms over any fixed overlap function or grouping function. First, we introduce the concept of (alpha, O)-migrative uninorms over any fixed overlap function O. In addition, we show equivalent characterizations of the (alpha, O)-migrativity equation when the uninorm U belongs to one certain class (e.g. U-min, U-max , the family of idempotent uninorms, representable uninorms or uninorms continuous on ]0, 1[(2)). And then, we give the notion of (alpha, G)-migrative uninorms over any fixed grouping function G and propose the (alpha, G)-migrativity equation using an analogous method. Finally, we discuss the (alpha, O)-migrative and (alpha, G)-migrative nullnorms and obtain equivalent characterizations of the related (alpha, O)-migrativity and (alpha, G)-migrativity equations, respectively.
