Abstract
Integrable Kondo impurities in two cases of the one-dimensional t-J model a re studied by means of the boundary Z(2)-graded quantum inverse scattering method. The boundary K-matrices depending on the local magnetic moments of the impurities are presented as non-trivial realizations of the reflection equation algebras in an impurity Hilbert space. Furthermore, these models a re solved by using the algebraic Bethe ansatz method and the Bethe ansatz e quations are obtained. (C) 1999 Elsevier Science B.V.
