Eigenvalues of the tetradiagonal Toeplitz matrices with diagonals 1, 0, 0, 1

Sergei M. Grudsky, Román Higuera-García, Egor A. Maximenko +1

We perform a thorough analysis of the eigenvalues of tetradiagonal Toeplitz matrices of large order $n$ generated by the Laurent polynomial $a (t) = t^{2} + t^{- 1}$ . The spectra of these…

Eigenvalues of one family of tridiagonal skew-self-adjoint Toeplitz matrices with complex perturbations on the corner

C. Bernardin, S. M. Grudsky, E. A. Maximenko +1

In this paper, we study the eigenvalues of the matrices $T_{n} (a) + γ E_{n, 1, 1}$ where $T_{n} (a)$ is the Toeplitz matrix with generating symbol $a (t) = t - t^{- 1}$ , $E_{n, 1, 1}$ is the $n\time…
