Abstract. Two high-dimensional Lie algebras are presented for which four ()-dimensional expanding integrable couplings of the D-AKNS hierarchy are obtained by using the Tu scheme; one of them is a united integrable coupling model of the D-AKNS hierarchy and the AKNS ()-dimensional DS hierarchy is derived by using the TAH scheme; in particular, Cited by: 6.

Earlier results of Moser on rank 2 extensions of a fixed matrix can be incorporated into this framework, which implies in particular that many well-known integrable systems—such as the Neumann system, periodic Toda, geodesic flow on an.

The theory of classical R-matrices provides a unified approach to the understanding of most, if not all, known integrable systems.

This work, which is suitable as a graduate textbook in the modern theory of integrable systems, presents an exposition of R-matrix theory by means of examples, some old, some new.

The book begins by introducing the central ideas of the theory of integrable systems, based on Lax representations, loop groups and Riemann : Olivier Babelon, Denis Bernard, Michel Talon.

Originally a model for wave propagation on the line, the Toda lattice is a wonderful case study in mechanics and symplectic geometry. In Flaschka's variables, it becomes an evolution given by a Lax pair on the vector space of real, symmetric, tridiagonal matrices.
