【摘要】 The hierarchies of theμ-Camassa-Holm,two-componentμ-Camassa-Holm andμ-modified Camassa-Holm equations are constructed from bi-Hamiltonian structures of the Korteweg-de Vries equation,the Ito equation and the modified Korteweg-de Vries equation.The key Hamiltonian operator that includesμis(?)_xμ-(?)_x~3,and the inner product used to define the Jacobi identity of the Hamiltonian operators is defined on the unit circle S~1.
