摘要
Two types of Lie algebras, which are the subalgebras of the Lie algebra A(2), A(3) respectively, are presented. The resulting loop algebras are following. As their applications, two different integrable couplings of the Yang hierarchy are obtained, called them the double integrable couplings. The Hamiltonian structure of one of them is worked out by a proper linear isomorphic transformation and the quadratic-form identity. (C) 2006 Elsevier Ltd. All rights reserved.
