On the migrativity of 2-uninorms

This article focuses on the alpha-migrativity of 2-uninorms with alpha is an element of [0, 1]. It characterizes the alpha-migrativity for 2-uninorms with alpha is an element of [0, 1], which generalizes and unifies the characterizations for some existing alpha-migrativity of uni-nullnorms, null-uninorms, uninorms and nullnorms, respectively. It also proves that for every 2-uninorm U1 (resp. U2) and alpha is an element of [0, 1], there always exists a 2-uninorm U2 = U1 (resp., U1 = U2) such that U1 is alpha-migrative over U2.
