General decay in a Timoshenko-type system with thermoelasticity with second sound
Advances in Nonlinear Analysis, 2015 In this article, we consider a vibrating nonlinear Timoshenko system with thermoelasticity with second sound. We discuss the well-posedness and the regularity of solutions using the semi-group theory.

On a criterion of Yakubovich type for the absolute stability of nonautonomous control processes
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 16, Page 1027-1041, 2003., 2003 We generalize a criterion of Yakubovich for the absolute stability of control processes with periodic coefficients to the case when the coefficients are bounded and uniformly continuous functions.

Strict diagonal dominance in asymptotic stability of general equilibrium
Fixed Point Theory and Applications, 2013 Stability of general equilibrium is usually depicted by a dynamic process of price adjustment which makes the flow of prices eventually come to rest at certain prices, so that the supply and demand of every commodity tend to equal each other.

Matrix measure and application to stability of matrices and interval dynamical systems
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 2, Page 75-85, 2003., 2003 Using some properties of the matrix measure, we obtain a general condition for the stability of a convex hull of matrices that will be applied to study the stability of interval dynamical systems. Some classical results from stability theory are reproduced and extended.

Dynamics of a class of uncertain nonlinear systems under flow‐invariance constraints
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 5, Page 263-294, 2003., 2003 For a class of uncertain nonlinear systems (UNSs), the flow-invariance of a time‐dependent rectangular set (TDRS) defines individual constraints for each component of the state‐space trajectories. It is shown that the existence of the flow‐invariance property is equivalent to the existence of positive solutions for some differential inequalities with ...

STABILITY ANALYSIS OF SWITCHED DISCRETE TIME-DELAY SYSTEMS WITH CONVEX POLYTOPIC UNCERTAINTIES
, 2014 This article is concerned with robust stability of switched discrete time-delay systems with convex polytopic uncertainties. The system to be considered is subject to interval time-varying delays, which allows the delay to be a fast time-varying function

[Retracted] On the interlacing property and the Routh‐Hurwitz criterion
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 12, Page 727-737, 2003., 2003 Unlike the Nyquist criterion, root locus, and many other stability criteria, the well‐known Routh‐Hurwitz criterion is usually introduced as a mechanical algorithm and no attempt is made whatsoever to explain why or how such an algorithm works. It is widely believed that simple derivations of this important criterion are highly requested by the ...

On the Lyapunov equation in Banach spaces and applications to control problems
International Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 3, Page 155-166, 2002., 2002 By extending the Lyapunov equation A*Q + QA = −P to an arbitrary infinite‐dimensional Banach space, we give stability conditions for a class of linear differential systems. Relationship between stabilizability and exact null‐controllability is established.

Numerical solution of fractional Mathieu equations by using block-pulse wavelets
Journal of Ocean Engineering and Science, 2019 In this paper, we introduce a method based on operational matrix of fractional order integration for the numerical solution of fractional Mathieu equation and then apply it in a number of cases.

New approach to asymptotic stability: time‐varying nonlinear systems
International Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 2, Page 347-366, 1997., 1995 The results of the paper concern a broad family of time‐varying nonlinear systems with differentiable motions. The solutions are established in a form of the necessary and sufficient conditions for: 1) uniform asymptotic stability of the zero state, 2) for an exact single construction of a system Lyapunov function and 3) for an accurate single ...
