Explicit inverse of symmetric, tridiagonal near Toeplitz matrices Part II: with weakly diagonally dominant Toeplitz

Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek

In this paper, we provide explicit formulas for the exact inverses of the symmetric tridiagonal near-Toeplitz matrices characterized by weak diagonal dominance in the Toeplitz part…

Explicit inverse of symmetric, tridiagonal near Toeplitz matrices with strictly diagonally dominant Toeplitz part

Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek

This study investigates tridiagonal near-Toeplitz matrices in which the Toeplitz part is strictly diagonally dominant. The focus is on determining the exact inverse of these matric…

Inverse properties of a class of pentadiagonal matrices related to higher order difference operators

Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek

This paper analyzes the convergence of fixed-point iterations of the form u = f(u) and the properties of the inverse of the related pentadiagonal matrices, associated with the four…

Inverse properties of a class of seven-diagonal (near) Toeplitz matrices

Bakytzhan Kurmanbek, Yogi Erlangga, Yerlan Amanbek

This paper discusses the explicit inverse of a class of seven-diagonal (near) Toeplitz matrices, which arises in the numerical solutions of nonlinear fourth-order differential equa…

A proof of Anđelić-Fonseca conjectures on the determinant of some Toeplitz matrices and their generalization

Bakytzhan Kurmanbek, Yerlan Amanbek, Yogi Erlangga

We present a proof of determinant of special nonsymmetric Toeplitz matrices conjectured by Anđelić and Fonseca in \cite{andjelic2020some}. A proof is also demonstrated for a more g…
