On the squared eigenfunction symmetry of the Toda lattice hierarchy
Jipeng Cheng, Jingsong He
The squared eigenfunction symmetry for the Toda lattice hierarchy is explicitly constructed in the form of the Kronecker product of the vector eigenfunction and the vector adjoint…
The integral type gauge transformation and the additional symmetry for the constrained KP hierarchy
Jipeng Cheng, Jingsong He
In this paper, the compatibility between the integral type gauge transformation and the additional symmetry of the constrained KP hierarchy is given. And the string-equation constr…
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…
