Abstract: | The trace identity is extended to the quadratic-form identity. The Hamiltonian
structures of the multi-component Guo hierarchy, integrable coupling of Guo
hierarchy and (2+1)-dimensional Guo hierarchy are obtained by the quadratic-form
identity. The method can be used to produce the Hamiltonian structures of the other
integrable couplings or multi-component hierarchies. |
