Migrativity equations and Mayor's aggregation operators

There has been a growing interest in the study of the notion of -migrativity and generalizations in recent years, and it has been investigated for families of certain operators such as t-norms, t-conorms, uninorms, nullnorms. This paper is mainly devoted to investigating the migrativity equations between semi-t-operators or semi-uninorms, and Mayor's aggregation operators. The results that we obtain are complete and dierent from the known ones concerning migrativity for t-norms, t-conorms, uninorms and nullnorms.
