Solving bi-directional soliton equations in the KP hierarchy by gauge transformation
Jingsong He, Yi Cheng, Rudolf A. Roemer
We present a systematic way to construct solutions of the (n=5)-reduction of the BKP and CKP hierarchies from the general tau function of the KP hierarchy. We obtain the one-solito…

Hamiltonian Structures of KdV-Type Hierarchies and Associated W-Algebras
Yi Cheng, Qing Chen, Jingsong He
The KdV hierarchy is a restriction of the KP hierarchy to a submanifold of pseudo-differential operators in a radio form. Explicit formula of the restricted Hamiltonian s…

Bethe Ansatz and Quantum Davey-Stewartson 1 System with Multicomponent in Two Dimensions
Yi Cheng, Mu-Lin Yan, Bao-Heng Zhao
The quantum 2-component DS1 system was reduced to two 1D many-body problems with function interactions, which were solved by Bethe ansatz. Using the ansatz in ref.[1] and intro…
