两个矩阵之和的Drazin逆的表示
Representations for Drazin Inverses of Sum of Two Matrices
摘要
Abstract
We considered representations for Drazin inverses of the sum of two matrices,under the condition of A DB =0,AB D =0,BπABAAπ=0,BπAB 2 Aπ=0 for the n order matrix A and B .We gave representations for Drazin inverses of A+B by using the core-nilpotent decomposition of matrices.关键词
