Abstract
Let A and B be nonsingular M-matrices. Some new lower bounds on the minimum eigenvalue
q
(
A
∘
B
−

)
for the Hadamard product of A and
B
−
1
are given. These bounds improve the corresponding results of Chen (Linear Algebra Appl. 378:159-166, 2004) and Huang (Linear Algebra Appl. 428:1551-1559, 2008) and generalize the corresponding result of Xiang (Linear Algebra Appl. 367:17-27, 2003).
