Three New Proofs of the Theorem rank f(M) + rank g(M) = rank (f,g)(M) + rank [f,g](M)

open access: yesMathematics
It is well known that in C[X], the product of two polynomials is equal to the product of their greatest common divisor and their least common multiple. In a recent paper, we proved a similar relation between the ranks of matrix polynomials.

A Modified Vector Fitting Technique to Extract Coupling Matrix from S-parameters [PDF]

open access: yesRadioengineering, 2023
In this paper, a modified vector fitting technique to extract coupling matrix from S-parameters is introduced. This work allows designers to extract the coupling matrix of different or any pre-defined topologies from the simulated or measured S-parameter

Autocorrelation of Random Matrix Polynomials [PDF]

open access: yesCommunications in Mathematical Physics, 2003
We calculate the autocorrelation functions (or shifted moments) of the characteristic polynomials of matrices drawn uniformly with respect to Haar measure from the groups U(N), O(2N) and USp(2N). In each case the result can be expressed in three equivalent forms: as a determinant sum (and hence in terms of symmetric polynomials), as a combinatorial sum,

Some relations on Konhauser matrix polynomials

open access: yes, 2016
. This paper deals with the study of the generalized hypergeometric matrix function and obtains some of its properties. We rephrase some results from the previous (earlier) works that will be used in this study.

On generalized bihyperbolic third-order Jacobsthal polynomials [PDF]

open access: yesMathematica Bohemica
A new generalization of third-order Jacobsthal bihyperbolic polynomials is introduced. Some of the properties of presented polynomials are given. A general Vajda formula for the generalized bihyperbolic third-order Jacobsthal polynomials is obtained ...

On the sign characteristics of Hermitian matrix polynomials

open access: yes, 2016
The sign characteristics of Hermitian matrix polynomials are discussed, and in particular an appropriate definition of the sign characteristics associated with the eigenvalue infinity.

On characteristic and permanent polynomials of a matrix

open access: yesSpecial Matrices, 2017
There is a digraph corresponding to every square matrix over ℂ. We generate a recurrence relation using the Laplace expansion to calculate the characteristic and the permanent polynomials of a square matrix.
