Generating mechanism and dynamic of the smooth positons for the derivative nonlinear Schrödinger equation
Wenjuan Song, Shuwei Xu, Maohua Li +1
Based on the degenerate Darboux transformation, the -order smooth positon solutions for the derivative nonlinear Schrödinger equation are generated by means of the general deter…
The compatibility of additional symmetry and gauge transformations for the constrained discrete Kadomtsev-Petviashvili hierarchy
Maohua Li, Jipeng Cheng, Jingsong He
In this paper, the compatibility between the gauge transformations and the additional symmetry of the constrained discrete Kadomtsev-Petviashvili hierarchy is given, which preservi…
The wronskian solution of the constrained discrete KP hierarchy
Maohua Li, Jingsong He
From the constrained discrete KP (cdKP) hierarchy, the Ablowitz-Ladik lattice has been derived. By means of the gauge transformation, the Wronskian solution of the Ablowitz-Ladik l…
The gauge transformation of the constrained semi-discrete KP hierarchy
Maohua Li, Jipeng Cheng, Jingsong He
In this paper, the gauge transformation of the constrained semi-discrete KP(cdKP) hierarchy is constructed explicitly by the suitable choice of the generating functions. Under the…
Virasoro type algebraic structure hidden in the constrained discrete KP hierarchy
Maohua Li, Chuanzhong Li, Keilei Tian +2
In this paper, we construct the additional symmetries of one-component constrained discrete KP (cdKP) hierarchy, and then prove that the algebraic structure of the symmetry flows i…
Ghost symmetry of the discrete KP hierarchy
Chuanzhong Li, Jipeng Cheng, Kelei Tian +2
In this paper, with the help of the function and ghost symmetry for the discrete KP hierarchy which is a semi-discrete version of the KP hierarchy, the ghost flow on its eigenf…
The Recursion operators of the BKP hierarchy and the CKP Hierarchy
Maohua Li, Jipeng Cheng, Chuanzhong Li +1
In this paper, under the constraints of the BKP(CKP) hierarchy, a crucial observation is that the odd dynamical variable can be explicitly expressed by the even dynamica…
