研究了2×2分块矩阵的Drazin逆.在一定条件下,给出了分块矩阵M的Drazin逆关于分块A、B、C、D的表达式。这些结果部分回答了坎贝尔在1983年提出的问题。
The Drazin inverse of a 2×2 block matrix is considered. Expressions for the Drazin inverse of block matrix M in terms of the individual blocks A B C, and D are delivered under some conditions. These results partially answer the question by Campbell in 1983.
