Abstract
The integrable open-boundary conditions for the model of three coupled one-dimensional XY spin chains are considered in the framework of the quantum inverse scattering method. The diagonal boundary K-matrices a re found and a class of integrable boundary terms is determined. The b oundary model Hamiltonian is solved by using the coordinate space Beth e ansatz technique and Bethe ansatz equations are derived. (C) 1998 El sevier Science B.V.
