A Decreasing Sequence of Eigenvalue Localization Regions

Abstract We construct a decreasing sequence of rectangles (Rp) in such a way that all the eigenvalues of a complex matrix A are contained in each rectangle. When A is a matrix with real spectrum or a normal matrix, each Rp can be obtained without knowing the eigenvalues of A.
