Abstract:The hierarchies of the μ-Camassa–Holm, two-component μ-Camassa–Holm and μ-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 includes μ is ?x μ??3x, and the inner product used to define the Jacobi identity of the Hamiltonian operators is defined on the unit circle S1.
