Abstract

Abstract Identified are certain special periodic diagonal matrices that have a predictable number of pairedeigenvalues. Since certain symmetric Toeplitz matrices are special cases, those that have several multiple 5eigenvalues are also investigated further. This work generalizes earlier work on response matrices from circularlysymmetric models.
