Fast iterative solutions of Riccati and Lyapunov equations

open access: yesOpen Mathematics, 2022
In this article, new iterative algorithms for solving the discrete Riccati and Lyapunov equations are derived in the case where the transition matrix is diagonalizable with real eigenvalues.

Tolerability and the effect on skin Staphylococcus pseudintermedius density of repeated diluted sodium hypochlorite (bleach) baths at 0.005% in healthy dogs

open access: yesVeterinary Dermatology, Volume 34, Issue 6, Page 489-494, December 2023., 2023
Background – Dilute sodium hypochlorite (bleach) baths at 0.005% concentration twice weekly have been shown to markedly reduce the severity of atopic dermatitis in children, yet no tolerability and efficacy data are available for this treatment in dogs.

W-MPD–N-DMP-solutions of constrained quaternion matrix equations

open access: yesSpecial Matrices, 2023
The solvability of several new constrained quaternion matrix equations is investigated, and their unique solutions are presented in terms of the weighted MPD inverse and weighted DMP inverse of suitable matrices.

Evaluation of the effects of chlorhexidine digluconate with and without cBD103 or cCath against multidrug‐resistant clinical isolates of Staphylococcus pseudintermedius

open access: yesVeterinary Dermatology, Volume 33, Issue 1, Page 17-e6, February 2022., 2022
Background – Because of the increased incidence of multidrug‐resistant (MDR) bacteria, the use of disinfectants over antibiotics has been encouraged. However, the interactions between disinfectants and host local immunity are poorly understood. Objective – To assess the effects of chlorhexidine digluconate (Chx), with and without selected host defence ...

Matrix representation of a cross product and related curl-based differential operators in all space dimensions

open access: yesOpen Mathematics, 2021
A higher dimensional generalization of the cross product is associated with an adequate matrix multiplication. This index-free view allows for a better understanding of the underlying algebraic structures, among which are generalizations of Grassmann’s ...

Characterizations of the group invertibility of a matrix revisited

open access: yesDemonstratio Mathematica, 2022
A square complex matrix AA is said to be group invertible if there exists a matrix XX such that AXA=AAXA=A, XAX=XXAX=X, and AX=XAAX=XA hold, and such a matrix XX is called the group inverse of AA.

Left and right inverse eigenpairs problem with a submatrix constraint for the generalized centrosymmetric matrix

open access: yesOpen Mathematics, 2020
Left and right inverse eigenpairs problem is a special inverse eigenvalue problem. There are many meaningful results about this problem. However, few authors have considered the left and right inverse eigenpairs problem with a submatrix constraint.

Invariance property of a five matrix product involving two generalized inverses

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
Matrix expressions composed by generalized inverses can generally be written as f(A−1, A−2, . . ., A−k), where A1, A2, . . ., Ak are a family of given matrices of appropriate sizes, and (·)− denotes a generalized inverse of matrix.

The 𝔪-WG° inverse in the Minkowski space

open access: yesOpen Mathematics, 2023
In this article, we study the m{\mathfrak{m}}-WG∘{}^{\circ } inverse which presents a generalization of the m{\mathfrak{m}}-WG inverse in the Minkowski space. We first show the existence and the uniqueness of the generalized inverse.

Some non-commuting solutions of the Yang-Baxter-like matrix equation

open access: yesOpen Mathematics, 2020
Let A be a square matrix satisfying A4=A{A}^{4}=A. We solve the Yang-Baxter-like matrix equation AXA=XAXAXA=XAX to find some solutions, based on analysis of the characteristic polynomial of A and its eigenvalues. We divide the problem into small cases so
