Enlarging spectral problems to construct integrable couplings of soliton equations. (English) Zbl 1042.37057
Summary: A way to construct integrable couplings of soliton equations is presented through enlarging spectral problems associated with soliton equations, and it is used to construct a class of integrable couplings of the AKNS soliton equations.
