| Abstract: |
| A linear isospectral problem is established by choosing a subalgebra of loop alge-bra A1, from which an integrable hierarchy of equations similar to the KN hierarchy is de-rived. A simple straightforward method for obtaining integrable couplings is proposed. Itfollows that the integrable coupling of the above hierarchy is obtained. This method can beused generally. |
