超对称可积系统和离散可积系统

Within the framework of this NNSFC project, we achieved the followings: Darboux transformations are constructed for the supersymmetric KP hierarchies; it is shown that the coupled KdV.of Nutku and Oguz can be decoupled; two Hamiltonian structures for the Ito’s equation are provided; it is proved that the Miura map between the lattice KP and modified lattice KP is canonical.in the sense of the second Hamiltonian structure; a Darboux transformation is given for the modified Veselov-Novikov equation; we also give an explanation of appearance of Pfaffian solutions.for the BKP hierarchy
