Stability and Instability Matrices for Linear Evolution Variational Inequalities [PDF]

open access: yesIEEE Transactions on Automatic Control, 2004
This paper deals with the characterization of the stability and instability matrices for a class of unilaterally constrained dynamical systems, represented as linear evolution variational inequalities (LEVI). Such systems can also be seen as a sort of differential inclusion, or (in special cases) as linear complementarity systems, which in turn are a ...

Inequalities for sector matrices and positive linear maps

open access: yesThe Electronic Journal of Linear Algebra, 2019
Ando proved that if A, B are positive definite, then for any positive linear map Φ, it holds Φ(A#λB) ≤ Φ(A)#λΦ(B), where A#λB, 0 ≤ λ ≤ 1, means the weighted geometric mean of A, B. Using the recently defined geometric mean for accretive matrices, Ando’s result is extended to sector matrices. Some norm inequalities are considered as well.

Finite time stability of linear time varying delay systems using free matrix based integral inequalities

open access: yesResults in Control and Optimization, 2023
This paper discusses the problem of finite time stability (FTS) for linear delayed systems where the time-varying delay is bounded. First, based on a Lyapunov–Krasovskii Functional (LKF) which contains terms of triple integrals, delay-dependent FTS ...

Social inequalities in vaccine coverage and their effects on epidemic spreading. [PDF]

open access: yesPLoS Computational Biology
Vaccinations are fundamental public health interventions. Yet, inequalities in vaccine uptake across socioeconomic groups can significantly undermine their impact.

Stability and Unstability Matrices for Linear Evolution Variational Inequalities [PDF]

open access: yes, 2003
This paper deals with the characterisation of the stability and unstability matrices for a class of unilaterally constrained dynamical systems, represente- d as linear evolution variational inequalities (LEVI). Such systems can also be seen as a sort of differential inclusion, or (in special cases) as linear complementarity systems, which in turn are a

Inequalities for positive linear maps on Hermitian matrices [PDF]

open access: yesMathematical inequalities & applications, 2000
As a continuation of \cite{; ; MSTT}; ; , we shall discuss complementary results to Jensen's type inequalities on the Hadamard product of positive operators, which is based on the idea due to Furuta and Mond-Pečarić. We shall show Hadamard product versions of operator inequalities associated with extensions of H\"{; ; ; o}; ; ; lder-McCarthy and ...

Linear maps of positive partial transpose matrices and singular value inequalities [PDF]

open access: yesMathematical Inequalities & Applications, 2020
Let \(\mathbb{M}_n\) be the set of complex \(n\times n\) matrices, and let \(\mathbb{M}_m(\mathbb{M}_n)\) be the set of \(m\times m\) block matrices with each block in \(\mathbb{M}_n\). The partial transpose of \(\mathbf{A}=[A_{ij}]_{i,j=1}^m\in\mathbb{M}_m(\mathbb{M}_n)\) is \(\mathbf{A}^\tau=[A_{ji}]_{i,j=1}^m\).
