If A is a nonsingular M-matrix, some new upper and lower boundson the minimum eigenvalue (A) of A are given. These bounds improvesome results of Tian and Huang and are more accurate than Li et al. insome cases. In addition, we obtain some new bounds on the minimumeigenvalue of a nonsingular M-matrix A , which can give a rmativeconclusions about whether bounds for the minimum eigenvalue of ageneral nonsingular M-matrix A are only depending on the entries of Aand they are easy to calculate.
