Abstract
The discrete version of the inverse scattering method proposed by Ablo witz and Ladik is extended to solve multi-component systems. The exten sion enables one to solve the initial value problem, which proves dire ctly the complete integrability of a semi-discrete version of the coup led modified Korteweg-de Vries (KdV) equations and their hierarchy. It also provides a procedure to obtain conservation laws and multi-solit on solutions of the hierarchy. (C) 1998 American Institute of Physics.
