摘要 文章在A,B是非奇M-矩阵的条件下,给出了B与A-1的Hadamard积B°A-1的最小特征值τ(B°A-1)的一个下界。另外,还得到了非奇M-矩阵A与其逆A-1的Hadamard积的最小特征值的一个下界。 If A and B are nonsingular M-matrices, the Hadamard product of B and A- is given. In addition, M-matrix A and its inverse A- is derived. a lower bound on the minimum eigenbalue r (BoA-1) for a lower bound of the minimum eigenvalue r (AoA-1) of an
