The Eigenproblem and Invariant Subspaces: Perturbation Theory

  • Ilse C. F. Ipsen
Part of the Contemporary Mathematicians book series (CM)


In this collection of papers, Pete Stewart established the foundations for the perturbation theory of invariant subspaces. He introduced two crucial concepts that allow a systematic approach toward such a perturbation theory: subspace rotation and operator separation. These two concepts form the guiding principle in most of these papers.
