An Integrable so(3, RR)-Counterpart of the Heisenberg Soliton Hierarchy

An integrable counterpart of the Heisenberg soliton hierarchy is generated from a matrix spectral problem associated with so(3, RR). Bi-Hamiltonian structures of the resulting counterpart soliton hierarchy are furnished by the trace identity, and all newly presented equations are shown to possess infinitely many commuting symmetries and conservation laws.
