The main contents of the book include
the following: In chapter 2， we would
liketo present a definition of the bi-
integrable couplings of continuous and
discrete solitonhierarchies， which contain
two given integrable equations as their
sub-systems. Thereare much richer
mathematical structures behind bi-integrable
couplings than scalarintegrable equations.
And it is shown that such bi-integrable
coupling system canpossess zero curvature
representation and algebraic structure
associated with semi-direct sums of Lie
algebras. As application examples of the
algebraic structure， thebi-integrable
coupling system of the MKdV and generalized
Toda lattice equationhierarchies are
presented from this theory.
In chapter 3，it is shown that the
Kronecker product of matrix Lie algebra
canbe applied to construct a new integrable
coupling system and Hamiltonian struc-tures
of continuous and discrete soliton
hierarchies. Furthermore， we construct
theHamiltonian structure of integrable
couplings of soliton hierarchy by using the
Kro-necker product. The key steps aim at
constructing a new Lax pairs by the
Kroneckerproduct. As illustrate examples，
direct application to the continuous and
discretespectral problems lead to some novel
soliton equation hierarchies of integrable
cou-pling system. Then， we present the
Hamiltonian structure of integrable
couplings ofcontinuous and discrete
hierarchies with the component-trace
identity.
