Abstract：
Suppose both A and B are n×n nonsingular M-matrices. An estimate from below for the smallest eigenvalue τ(A○B-1) (in modulus) of the Hadamard product A○B-1 of A and B-1 is derived. As a special case, we obtain the inequality τ(A ○ A-1) ≥ 2/n (n ≥ 2). © 2003 Elsevier Inc. All rights reserved.
