摘要：
The so(5)(i.e., B-2) quantum integrable spin chains with both periodic and non-diagonal boundaries are studied via the off-diagonal Bethe Ansatz method. By using the fusion technique, sufficient operator product identities (comparing to those in [1]) to determine the spectrum of the transfer matrices are derived. For the periodic case, we recover the results obtained in [1], while for the non-diagonal boundary case, a new inhomogeneous T - Q relation is constructed. The present method can be directly generalized to deal with the so(2n + 1) (i.e., B-n) quantum integrable spin chains with general boundaries. (C) 2019 The Author(s). Published by Elsevier B.V.
