Abstract:Some new lower bounds of the minimum eigenvalue of Hadamard product A B-1 for M-matrix A and the inverse of M-matrix B are given. The given numerical examples show that estimating formules of the bounds are better than seversl known estimating formulas.
Keywords:M-matrix  Hadamard product  Perron vector  minimum eigenvalue
