Perturbation of Purely Imaginary Eigenvalues of Hamiltonian Matrices under Structured Perturbations
Please always quote using this URN:urn:nbn:de:0296-matheon-4217
- We discuss the perturbation theory for purely imaginary eigenvalues of Hamiltonian matrices under Hamiltonian and non-Hamiltonian perturbations. We show that there is a substantial difference in the behavior under these perturbations. We also discuss the perturbation of real eigenvalues of real skew-Hamiltonian matrices under structured perturbations and use these results to analyze the properties of the URV method of computing the eigenvalues of Hamiltonian matrices.
