Asymptotic stability of a Korteweg–de Vries equation with a two-dimensional center manifold

open access: yesAdvances in Nonlinear Analysis, 2018
Local asymptotic stability analysis is conducted for an initial-boundary-value problem of a Korteweg–de Vries equation posed on a finite interval [0,2⁢π⁢7/3]{[0,2\pi\sqrt{7/3}]}.

Stability analysis of the projectile based on random center manifold reduction

open access: yesTheoretical and Applied Mechanics Letters, 2023
The center manifold method has been widely used in the field of stochastic dynamics as a dimensionality reduction method. This paper studied the angular motion stability of a projectile system under random disturbances.

On oscillation of solutions of scalar delay differential equation in critical case

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper we study the oscillation problem for the known scalar delay differential equation. We assume that the coefficients of this equation have an oscillatory behaviour with an amplitude of oscillation tending to zero at infinity.

Approximations of center manifolds for delay stochastic differential equations with additive noise

open access: yesAdvances in Nonlinear Analysis, 2023
This article deals with approximations of center manifolds for delay stochastic differential equations with additive noise. We first prove the existence and smoothness of random center manifolds for these approximation equations. Then we show that the Ck{

The Grassmann-like manifold of centered planes when a surface is described by the centre

open access: yesДифференциальная геометрия многообразий фигур, 2021
We continue to study of the Grassmann-like manifold of -centered planes. A special case is considered when the center de­scribes an -dimensional surface . We will denote this mani­fold by . An analogue of the strong Norden normalization of the manifold

Stability Switches and Double Hopf Bifurcation Analysis on Two-Degree-of-Freedom Coupled Delay van der Pol Oscillator

open access: yesMathematics, 2021
In this paper, the normal form and central manifold theories are used to discuss the influence of two-degree-of-freedom coupled van der Pol oscillators with time delay feedback. Compared with the single-degree-of-freedom time delay van der Pol oscillator,
