Abstract
We study the perturbation theory for the eigenvalue problem of a formal matrix product A s1 1 ··· A sp p, where all A k are square and s k ∈ {−1, 1}. We generalize the classical perturbation results for matrices and matrix pencils to perturbation results for generalized deflating subspaces and eigenvalues of such formal matrix products. As an application we then extend the structured perturbation theory for the eigenvalue problem of Hamiltonian matrices to Hamiltonian/skew-Hamiltonian pencils.
