摘要

A new simple method for obtaining integrable hierarchies of soliton equations is proposed. First of all, a new loop algebra G_M is constructed, whose commutation operation is clear as that in loop algebra A_1. Second, by making use of Tu scheme, many of integrable hierarchies with multicomponent potential functions can be produced. As a specific application of our method, a multicomponent AKNS hierarchy is obtained. Finally, an expanding loop algebra F_M of the loop algebra G is constructed. Taking advantage of F_M above, a type of integrable coupling system of the multicomponent AKNS hierarchy is worked out.
