The new invariant currents were built in the case of the torsion components independence on coordinate and its equality to the structural constants of Lie algebras SU (n), SO (n) or SP (n). We obtain a new equations for the primary chiral currents, including the completely symmetrical invariant tensors constructed from the structural constants of SU (n), SO (n), SP (n) algebras. The coherent nonlinear dissipative structures in plasma, including the waves unstable in the linear theory, are obtained. The model system of equations is chosen and the main nonlinear wave equation is derived as a result of regularization of the perturbation theory. It is proved that the wave dispersion, instability increments (damping) are defined by gradient of logarithm of unperturbed or nonequilibrium plasma density. The self-influence of waves with cubic nonlinearities that are destabilizing without the additives obtained from regularization of the perturbation theory is studied. The threshold values of the linear theory are researched.
