摘要

The Perk-Schultz model with SUq(m｜n) spin boundary impurities is constructed by dressing the c-number reflecting K-matrix with the local L-matrix which acts non-trivially on an impurity Hilbert space. The eigenvalue of the transfer matrix and the corresponding Bethe ansatz equations with different c-number reflecting K-matrices are obtained by using the nested Bethe ansatz method (m ≠ n). When m ＝ 1,n ＝ 2, our results come back to that of supersymmetric t - J model with SUq(1｜2) spin boundary impurities.
