Abstract:

We address Drazin inverse of the addition of two matrices. We present a new proof approach of Drazin inverse of the addition of two matrices in some given conditions with the separation of a block matrix into two triangular matrices and the relevant properties of Drazin inverse.

Key words: matrix addition, triangular matrix, Drazin inverse
