摘　　要：利用带W权Drazin逆的代数结构,将方阵的Drazin逆的{1}-逆表示与极限表示推广到长方阵的情况,得到长方阵带W权Drazin逆的{1}-逆表示与极限表示.In this paper,we use the algebraic structures of A,W and W-weighted Drazin inverse to present the{1}-inverse representation and the limiting representation of the W-weighted Drazin inverse for the rectangular matrix.

关 键 词：加权DRAZIN逆 指标 {1}-逆表示 极限表示
