摘　　要：研究逆M-矩阵的结构性质和五对角逆M-矩阵在Hadamard积下的封闭性,分析五对角逆M-矩阵和广义Hessenberg逆M-矩阵的优美的组合性质,证明了广义Hessenberg逆M-矩阵与其转置矩阵在Hadamard积下是封闭的.In this paper,we concern with the structural properties of inverse M-matrices and the closure properties of five-diagonal inverse M-matrices under Hadamard product.Combinatorial properties of five-diagonal inverse M-matrices and generalized Hessenberg inverse M-matrices are analyzed,it is proved that a generalized Hessenberg inverse M-matrix and its transpose is closed under Hadamard product.

关 键 词：五对角矩阵 HADAMARD积 逆M-矩阵 M-矩阵
