Abstract:

Based on fractional isospectral problems and general bilinear forms, the gener-alized fractional trace identity is presented. Then, a new explicit Lie algebra is introduced for which the new fractional integrable couplings of a fractional soliton hierarchy are derived from a fractional zero-curvature equation. Finally, we obtain the fractional Hamiltonian
structures of the fractional integrable couplings of the soliton hierarchy.

Key words: generalized fractional trace variational identity, fractional integrable cou-plings, soliton hierarchy, Hamiltonian structure
