Locality of the conservation laws for the soliton equations related to Caudrey-Beals-Coifman system. (English) Zbl 1305.35125

Summary: We consider the hierarchies of nonlinear evolution equations related to auxiliary problem of Caudrey-Beals-Coifman type. We give a proof that the conservation laws for these equations have local densities based on the theory of the generating operators related to the Caudrey-Beals-Coifman linear problem.
