An integrable couplings of G-WKI equations hierarchy with self-consistent sources

Abstract: We present a kind of integrable couplings of soliton equations hierarchy with self-consistent sources by using the loop algebra . As an application, a new integrable couplings of the generalized Wadati–Konono–Ichikawa (G-WKI) equations hierarchy with self-consistent sources is derived through the enlarged loop algebra .
