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

Sergei M. Grudsky, RomÃ¡n Higuera-GarcÃa, Egor A. Maximenko +1

The paper studies the eigenvalues of large tetradiagonal Toeplitz matrices generated by the Laurent polynomial t²+t⁻¹, deriving asymptotic formulas for their distribution and confi…

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 $T_{n} (a) + I^^{3} E_{n, 1, 1}$ where $T_{n} (a)$ is the Toeplitz matrix with generating symbol $a (t) = t - t^{- 1}$ , $E_{n, 1, 1}$ is the $n\tim…
