摘要： 该文获得了M矩阵的Oppenheim型不等式(该问题为公开问题),即
det (A·B)≥(Πi=1nbii) let A
其中A,B=(bij)为n阶一般地矩阵,A·B为A与B的Fan积.

Abstract: In this paper, the Oppenheim-like inequality for the general M-ma-trices is obtained, i.e., det(A·B) ≥ (Πi=1nbii) det A for general M-matrices A and B of order n.

Key words: matrix, inequality, determinant, M-matrix, Oppenheim inequality
