The norm of an infinite L-matrix
Operators and Matrices, 2021 Evaluating the norm of infinite matrices, as operators acting on the sequence space 2 , is not an easy task. For a few celebrated matrices, e.g., the Hilbert matrix and the Cesàro matrix, the precise value of the norm is known.

Inequalities Involving Companion Matrix
Theoretical Mathematics and Applications, 2022 We give several inequalities involving the Frobenius companion matrix of a polynomial P, and solve any equation in involving c, c2, and c3. 2010 Mathematics Subject Classification: 15A60, 12D10. Keywords and phrases: Bounds for the zeros of polynomials,

Journal of Mathematical Inequalities, 2021 Convex functions have played a major role in the field of Mathematical inequalities. In this paper, we introduce a new concept related to convexity, which proves better estimates when the function is somehow more convex than another.

Veterinary Dermatology, Volume 34, Issue 6, Page 543-553, December 2023., 2023 Background – Hymenoptera envenomation with honey bee (Apis mellifera) and paper wasp (Polistes spp.) may cause life‐threatening anaphylaxis in dogs. In human patients, clinical history, intradermal testing (IDT) and measurement of allergen‐specific serological immunoglobulin (Ig)E (sIgE) are used to support a diagnosis of Hymenoptera venom ...

New determinantal inequalities concerning Hermitian and positive semi-definite matrices
Operators and Matrices, 2021 . Let A , B be n × n matrices such that A is positive semi-de fi nite and B is Hermitian. In this note, it is shown, among other inequalities, the following determinantal inequality det ( A k +( AB ) 2 ) (cid:2) det ( A k + A 2 B 2 ) for all k ∈ [ 1 , ∞ [

Veterinary 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 ...

On 3-by-3 row stochastic matrices
Special Matrices, 2023 The known constructive tests for the shapes of the numerical ranges in the 3-by-3 case are further specified when the matrices in question are row stochastic. Auxiliary results on the unitary (ir)reducibility of such matrices are also obtained.

Dynamical study of Lyapunov exponents for Hide’s coupled dynamo model
Demonstratio Mathematica, 2021 In this paper, we introduced the Lyapunov exponents (LEs) as a significant tool that is used to study the numerical solution behavior of the dynamical systems. Moreover, Hide’s coupled dynamo model presents a valuable dynamical study.

Integral representations of some families of operator monotone functions
Operators and Matrices, 2021 We obtain an integral representation of holomorphic function Pα(z) which is real on the positive part of the real axis and formed Pα(x) = ( xα +1 2 ) 1 α (x 0).
