Some Refined Eigenvalue Perturbation Bounds for Two-by-Two Block Hermitian Matrices
Published online by Cambridge University Press: 28 May 2015
Abstract
We consider eigenvalue perturbation bounds for Hermitian matrices, which are associated with problems arising in various computational science and engineering applications. New bounds are discussed that are sharper than some existing ones, including the well-known Weyl bound. Two numerical examples are investigated, to illustrate our theoretical presentation.
