摘要：
In this paper, we study the new lower bound for the minimum eigenvalue of the Hadamard product of an M-matrix and its inverse. The new lower bound improves the results of Li et al. [Y. T. Li, F. B. Chen, D. F. Wang, New lower bounds on eigenvalue of the Hadamard product of an M-matrix and its inverse, Lin. Alg. Appl. 430(2009)1423-1431.] and generalizes some corresponding results.
