Delay-dependent exponential stability of neutral stochastic delay systems [PDF]

open access: yes, 2009
This paper studies stability of neutral stochastic delay systems by linear matrix inequality (LMI) approach. Delay dependent criterion for exponential stability is presented and numerical examples are conducted to verify the effectiveness of the proposed

Stability calculations for piecewise-smooth delay equations [PDF]

open access: yes, 2008
This paper describes a new method for computing the stability of nonsmooth periodic orbits of piecewise-smooth dynamical systems with delay. Stability computations for piecewise-smooth dynamical systems without delay have previously been performed using ...

SEIR epidemiological model with varying infectivity and infinite delay [PDF]

open access: yes, 2008
A new SEIR model with distributed infinite delay is derived when the infectivity depends on the age of infection. The basic reproduction number R-0, which is a threshold quantity for the stability of equilibria, is calculated.

Reduction theories elucidate the origins of complex biological rhythms generated by interacting delay-induced oscillations. [PDF]

open access: yesPLoS ONE, 2011
Time delay is known to induce sustained oscillations in many biological systems such as electroencephalogram (EEG) activities and gene regulations. Furthermore, interactions among delay-induced oscillations can generate complex collective rhythms, which ...

Repellers in systems with infinite delay

open access: yesJournal of Mathematical Analysis and Applications, 1989
A very important model for the interaction of species is a set of autonomous functional differential equations \[ (*)\quad x'(t)=f(x_ t),\quad t\geq 0, \] where x: \({\mathbb{R}}\to {\mathbb{R}}^ n\) and \(x_ t\) is defined for \(t\geq 0\) by \(x_ t(s)=x(t+s)\) for \(-\infty

Stability and Boundedness of Stochastic Volterra Integrodifferential Equations with Infinite Delay

open access: yesJournal of Applied Mathematics, 2013
We make the first attempt to discuss stability and boundedness of solutions to stochastic Volterra integrodifferential equations with infinite delay (IDSVIDEs).

Approximate Controllability of Fractional Neutral Evolution Equations in Banach Spaces

open access: yesAbstract and Applied Analysis, 2013
We discuss the approximate controllability of semilinear fractional neutral differential systems with infinite delay under the assumptions that the corresponding linear system is approximately controllable.

Delay-dependent robust stability of stochastic delay systems with Markovian switching [PDF]

open access: yes, 2009
In recent years, stability of hybrid stochastic delay systems, one of the important issues in the study of stochastic systems, has received considerable attention. However, the existing results do not deal with the structure of the diffusion but estimate
