Algebra Seminar: A-Posteriori Error Bounds for Eigenvalue Perturbations
1:25pm, Neill 106W
Abstract: In this talk, I will address the question: How do the eigenvalues change if the entries of a matrix are slightly perturbed? I will talk about the general error bounds given by Bauer and Fike (1960), and Kahan, Partlett, and Jiang (1980), and their refinements. I will also give special attention to the case when the matrix is normal.
