Functions Generating Normal Toeplitz Matrices
N. L. Zamarashkin, E. E. Tyrtyshnikov, V. N. Chugunov Institute of Numerical Mathematics, Russian Academy of Sciences
Abstract:
To any complex function there corresponds a Fourier series, which is often associated with a sequence $\{T_n\}$ of Toeplitz $n\times n$ matrices. Functions whose Fourier series generate sequences of normal Toeplitz matrices are classified, and a procedure for constructing Fourier series for which the sequence $\{T_n\}$ contains an infinite subsequence of normal matrices is described.
Keywords:
complex Fourier series, normal matrix, Toeplitz matrix, Hermitian Toeplitz matrix, circulant matrix.
