Ela Perturbation

چکیده
In this paper, the perturbation problems of A (2) T,S are considered. By virtue of the gap between subspaces, we derive conditions that make the perturbation of A (2) T,S stable when T, S and A have suitable perturbations. At the same time, explicit formulas for perturbation of A (2) T,S and new results on perturbation bounds are obtained.

Ela Perturbation of the Generalized Drazin Inverse
In this paper, we investigate the perturbation of the generalized Drazin invertible matrices and derive explicit generalized Drazin inverse expressions for the perturbations under certain restrictions on the perturbing matrices.
متن کاملEla Sensitivity Analysis for the Multivariate
This paper concerns with the sensitivity analysis for the multivariate eigenvalue problem (MEP). The concept of a simple multivariate eigenvalue of a matrix is generalized to the MEP and the first-order perturbation expansions of a simple multivariate eigenvalue and the corresponding multivariate eigenvector are presented. The explicit expressions of condition numbers, perturbation upper bounds...
متن کاملEla Perturbation of Purely Imaginary Eigenvalues of Hamiltonian Matrices under Structured Perturbations∗
The perturbation theory for purely imaginary eigenvalues of Hamiltonian matrices under Hamiltonian and non-Hamiltonian perturbations is discussed. It is shown that there is a substantial difference in the behavior under these perturbations. The perturbation of real eigenvalues of real skew-Hamiltonian matrices under structured perturbations is discussed as well and these results are used to ana...
