On migrativity property for uninorms
Recently, (?,U0) ( ? , U 0 ) -migrative uninorms U were introduced and discussed, where U  and U0 U 0 are two uninorms with neutral element e . In this paper, we will further study (?,U2) ( ? , U 2 ) -migrative uninorms U1 U 1 , where U1 U 1 and U2 U 2 are two uninorms with different neutral elements e1 e 1 and e2 e 2 , respectively. All cases when the uninorm U1 U 1 and U2 U 2 are in different families out of the most usual classes of uninorms are analyzed, characterizing all solutions of the migrativity equation for some possible combinations of U1 U 1 and U2 U 2 .
