Perturbation Bound for the Drazin Inverse of the Matrix-Value Function

الملخص EN

The perturbation analysis of the differential for the Drazin inverse of the matrix-value function A(t)∈Cn×n is investigated.

An upper bound of the Drazin inverse and its differential is also considered.

Applications to the perturbation bound for the solution of the matrix-value function coefficients some matrix equations are given.
