Efficient Evaluation of Matrix Polynomials beyond the Paterson–Stockmeyer Method

open access: yesMathematics, 2021
Recently, two general methods for evaluating matrix polynomials requiring one matrix product less than the Paterson–Stockmeyer method were proposed, where the cost of evaluating a matrix polynomial is given asymptotically by the total number of matrix ...

Polynomial sequences generated by infinite Hessenberg matrices

open access: yesSpecial Matrices, 2017
We show that an infinite lower Hessenberg matrix generates polynomial sequences that correspond to the rows of infinite lower triangular invertible matrices. Orthogonal polynomial sequences are obtained when the Hessenberg matrix is tridiagonal. We study

The Extended Invariant Factor Algorithm with Application to the Forney Analysis of Convolutional Codes [PDF]

open access: yes, 1993
In his celebrated paper on the algebraic structure of convolutional codes, Forney showed that by using the invariant-factor theorem, one can transform an arbitrary polynomial generator matrix for an (n, k) convolutional code C into a basic (and ...

The structure of solutions of the matrix linear unilateral polynomial equation with two variables

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2017
We investigate the structure of solutions of the matrix linear polynomial equation $A(\lambda)X(\lambda)+B(\lambda)Y(\lambda)=C(\lambda),$ in particular, possible degrees of the solutions.

CHARACTERISTIC ANTIADJACENCY MATRIX OF GRAPH JOIN

open access: yesBarekeng, 2022
Let  be a simple, connected, and undirected graph. The graph  can be represented as a matrix such as antiadjacency matrix. An antiadjacency matrix for an undirected graph with order  is a matrix that has an order  and symmetric so that the ...

A Look at Generalized Degenerate Bernoulli and Euler Matrices

open access: yesMathematics, 2023
In this paper, we consider the generalized degenerate Bernoulli/Euler polynomial matrices and study some algebraic properties for them. In particular, we focus our attention on some matrix-inversion formulae involving these matrices.

Random Perturbations of Matrix Polynomials [PDF]

open access: yesJournal of Theoretical Probability, 2020
AbstractA sum of a large-dimensional random matrix polynomial and a fixed low-rank matrix polynomial is considered. The main assumption is that the resolvent of the random polynomial converges to some deterministic limit. A formula for the limit of the resolvent of the sum is derived, and the eigenvalues are localised.
