The bi-periodic Horadam sequence and some perturbed tridiagonal 2-Toeplitz matrices: A unified approach [PDF]

open access: yesHeliyon, 2022
In this note we consider the so-called bi-periodic Horadam sequences. Explicit formulas in terms of Chebyshev polynomials of the second kind and the determinant of some perturbed tridiagonal 2-Toeplitz matrices are established.

Determinants and inverses of perturbed periodic tridiagonal Toeplitz matrices [PDF]

open access: goldAdvances in Difference Equations, 2019
In this paper, we deal mainly with a class of periodic tridiagonal Toeplitz matrices with perturbed corners. By matrix decomposition with the Sherman–Morrison–Woodbury formula and constructing the corresponding displacement of matrices we derive the ...

On the connection between tridiagonal matrices, Chebyshev polynomials, and Fibonacci numbers

open access: yesActa Universitatis Sapientiae: Mathematica, 2020
In this note, we recall several connections between the determinant of some tridiagonal matrices and the orthogonal polynomials allowing the relation between Chebyshev polynomials of second kind and Fibonacci numbers.

Computing the Eigenvectors of Nonsymmetric Tridiagonal Matrices

open access: yesComputational Mathematics and Mathematical Physics, 2021
The computation of the eigenvalue decomposition of matrices is one of the most investigated problems in numerical linear algebra. In particular, real nonsymmetric tridiagonal eigenvalue problems arise in a variety of applications. In this paper the problem of computing an eigenvector corresponding to a known eigenvalue of a real nonsymmetric ...
