摘要
A Bargmann symmetry constraint is proposed for the Lax pairg and the adjoint Lax pairs of the Dirac systems.It is shown that the spatial part of the nonlinearized Lax pairs and adjoint Lax pairs is a finite dimensional Liouville integrable Hamiltonian system and that nnder the control of the spatial part,the time parts of the nonlinearized Lax pairs and adjoint Lax pairs are interpreted as a hierarchy of commntative,finite dimensional Lionville integrable Hamiltonian systems whose Hamiltonian functions consist of a series of integrals of motion for the spatial part.Moreover an involutive representation of solutions of the Dirac systema exhibits their integrability by quadratures.This kind of symmetry constraint procedure involving the spectral problem and the adjoint spectral problem is referred to as a binary nonlinearization technique like a binary Darboux transformation.
