Inversion of Parahermitian matrices [PDF]

open access: yes, 2010
Parahermitian matrices arise in broadband multiple-input multiple-output (MIMO) systems or array processing, and require inversion in some instances. In this paper, we apply a polynomial eigenvalue decomposition obtained by the sequential best rotation ...

图的Aα-特征多项式系数的一个注记(A note on the coefficients of the Aα-characteristic polynomial of a graph)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2019
Let G be a graph on n vertices, and let A( G ) and D ( G ) denote the adjacency matrix and the degree matrix of G, respectively. Define Aα ( G )= αD ( G )+( 1 - α ) A( G ) for any real α ∈ [ 0,1 ].

New Structured Matrix Methods for Real and Complex Polynomial Root-finding [PDF]

open access: yes, 2013
We combine the known methods for univariate polynomial root-finding and for computations in the Frobenius matrix algebra with our novel techniques to advance numerical solution of a univariate polynomial equation, and in particular numerical ...

Realization in Generalized State Space form for 2-D Polynomial System Matrices

open access: yesSultan Qaboos University Journal for Science, 2005
In this paper, a direct realization procedure is presented that brings a general 2-D polynomial system matrix to generalized state space (GSS) form, such that all the relevant properties including the zero structure of the system matrix are retained.

Chebyshev polynomial method to Landauer–Büttiker formula of quantum transport in nanostructures

open access: yesAIP Advances, 2020
The Landauer–Büttiker formula describes the electronic quantum transport in nanostructures and molecules. It will be numerically demanding for simulations of complex or large size systems due to, for example, matrix inversion calculations.

Computation of nonlinear eigenvalues based on the Ore determinant: preliminary results [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
The concept of eigenvalues has recently been generalized for nonlinear systems, but the method to find them is missing. Unlike the linear case, now one has to deal with non-commutative polynomials from the Ore ring. In the paper, the Ore determinant of a

Interactive certificate for the verification of Wiedemann's Krylov sequence: application to the certification of the determinant, the minimal and the characteristic polynomials of sparse matrices [PDF]

open access: yes, 2015
Certificates to a linear algebra computation are additional data structures for each output, which can be used by a-possibly randomized- verification algorithm that proves the correctness of each output.
