By means of the complex representation of the standard symplect form on R4N, and the constraint relations between the potential and the wave functions, the new completely integrable systems of the complex form are got. Therefore, the involutive solutions of the coupled AKNS-Kaup-Newell equation hierarchy are given.展开更多
