Stability Analysis of Analytical and Numerical Solutions to Nonlinear Delay Differential Equations with Variable Impulses

Discrete Dynamics in Nature and Society, 2017
A stability theory of nonlinear impulsive delay differential equations (IDDEs) is established. Existing algorithm may not converge when the impulses are variable.

The stability of Killing-Cauchy horizons in colliding plane wave space-times [PDF]

, 2004
It is confirmed rigorously that the Killing-Cauchy horizons, which sometimes occur in space-times representing the collision and subsequent interaction of plane gravitational waves in a Minkowski background, are unstable with respect to bounded ...

Existence theory for perturbed impulsive hyperbolic differential inclusions with variable times

Journal of Mathematical Analysis and Applications, 2007
This paper deals with the existence of solutions for perturbed impulsive hyperbolic differential inclusions with variable times. To this end the authors use a fixed point theorem for the sum of a contraction multivalued map and completely continuous map.

On exponential stability of functional differential equations with variable impulse perturbations

Differential and Integral Equations, 2014
We consider a class of functional differential equations subject to perturbations, which vary in time, and we study the exponential stability of solutions of these equations using the theory of generalized ordinary differential equations and Lyapunov functionals.

Evaluation of the Phase-Dependent Rhythm Control of Human Walking Using Phase Response Curves.

PLoS Computational Biology, 2016
Humans and animals control their walking rhythms to maintain motion in a variable environment. The neural mechanism for controlling rhythm has been investigated in many studies using mechanical and electrical stimulation. However, quantitative evaluation

Robust spiked random matrices and a robust G-MUSIC estimator [PDF]

, 2014
A class of robust estimators of scatter applied to information-plus-impulsive noise samples is studied, where the sample information matrix is assumed of low rank; this generalizes the study of (Couillet et al., 2013b) to spiked random matrix models.
