Multi-condition of stability for nonlinear stochastic non-autonomous delay differential equation [PDF]

open access: yesModern Stochastics: Theory and Applications, 2018
A nonlinear stochastic differential equation with the order of nonlinearity higher than one, with several discrete and distributed delays and time varying coefficients is considered.

Stability with nonlinearity in a sector [PDF]

open access: yesIEEE Transactions on Automatic Control, 1966
Recent investigations of the stability of a class of nonlinear systems have extended the results of Popov. The block diagram representation of the problem is shown in Fig. 1 where the linear part having a transfer function G(s) (satisfying certain conditions) is followed by a nonlinear gain K(\sigma) ranging from 0 to \infty.

On Global Dynamics of Three Dimensional Magnetohydrodynamics: Nonlinear Stability of Alfvén Waves [PDF]

open access: yes, 2016
Magnetohydrodynamics (MHD) studies the dynamics of magnetic fields in electrically conducting fluids. In addition to the sound wave and electromagnetic wave behaviors, magneto-fluids also exhibit an interesting phenomenon: They can produce the Alfvén ...

Practical challenges in data‐driven interpolation: Dealing with noise, enforcing stability, and computing realizations

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView., 2023
Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Global Nonlinear Stability of Schwarzschild Spacetime under Polarized Perturbations [PDF]

open access: yes, 2017
One of the major outstanding questions about black holes is whether they remain stable when subject to small perturbations. An affirmative answer to this question would provide strong theoretical support for the physical reality of black holes. This book

Nonlinear Stability of the Monotone Traveling Wave for the Isothermal Fluid Equations with Viscous and Capillary Terms

open access: yesMathematics, 2023
We prove the existence of the monotone traveling wave for the isothermal fluid equations with viscous and capillary terms by the planar dynamical system method.

Nonlinear Stability of Expanding Star Solutions of the Radially Symmetric Mass‐Critical Euler‐Poisson System [PDF]

open access: yes, 2016
We prove nonlinear stability of compactly supported expanding star solutions of the mass‐critical gravitational Euler‐Poisson system. These special solutions were discovered by Goldreich and Weber in 1980.
