Abstract

If A and B are n × n nonsingular M-matrices, a new lower bound for the minimum eigenvalue τ B ∘ A − 1 for the Hadamard product of B and A − 1 is derived. As a consequence, a new lower bound for the minimum eigenvalue τ A ∘ A − 1 for the Hadamard product of A and its inverse A − 1 is given. Theoretical results and an example demonstrate that the new bounds are better than some existing ones.
