报告摘要：In this talk, we introduce the k-constrained differential-difference Kadomtsev-Petviashvili hierarchy, wherein the special case of k=1 is corresponding to the squared wavefunctions symmetry. The Ragnisco-Tu hierarchy is derived as taking k=1, and a semi-discrete analogue of Yajima-Oikawa hierarchy is produced as taking k=2. The Lax equation and bilinear identities are constructed for the k-constrained differential -difference Kadomtsev-Petviashvili hierarchy. Finally, the solution by a subset of the Lie algebra is shown.
