摘要：
In this proceeding we present the nested Bethe ansatz for open spin chains of XXX-type, with arbitrary representations (i. e. "spins") on each site of the chain and diagonal boundary matrices (K+(u), K-(u)). The nested Bethe ansatz applies for a general K-(u), but a particular form of the K+(u) matrix. We give the eigenvalues, Bethe equations and the form of the Bethe vectors for the corresponding models. The Bethe vectors are expressed using a trace formula © 2011 Pleiades Publishing, Ltd.
