Stability problems and numerical integration on the Lie group SO(3) × R3 × R3

open access: yesOpen Mathematics, 2018
The paper is dealing with stability problems for a nonlinear system on the Lie group SO(3) × R3 × R3. The approximate analytic solutions of the considered system via Optimal Homotopy Asymptotic Method are presented, too.

Nonlinear thermo-mechanical stability of shear deformable FGM sandwich shallow spherical shells with tangential edge constraints

open access: yesVietnam Journal of Mechanics, 2017
This paper presents an analytical approach to investigate the nonlinear axisymmetric response of moderately thick FGM sandwich shallow spherical shells resting on elastic foundations, exposed to thermal environments and subjected to uniform external ...

Systematic Review of Geometrical Approaches and Analytical Integration for Chen’s System

open access: yesMathematics, 2020
The main goal of this paper is to present an analytical integration in connection with the geometrical frame given by the Hamilton–Poisson formulation of a specific case of Chen’s system. In this special case we construct an analytic approximate solution

Stable self-similar blowup in energy supercritical Yang-Mills theory

open access: yes, 2012
We consider the Cauchy problem for an energy supercritical nonlinear wave equation that arises in $(1+5)$--dimensional Yang--Mills theory. A certain self--similar solution $W_0$ of this model is conjectured to act as an attractor for generic large data ...

Nonlinear Stability of Asymptotic Suction [PDF]

open access: yesTransactions of the American Mathematical Society, 1984
The semigroup approach to the Navier-Stokes equation in halfspace is used to prove that the stability of the asymptotic suction velocity profile is determined by the eigenvalues of the classical Orr-Sommerfeld equation. The usual obstacle, namely, that the corresponding linear operator contains 0 0 in the spectrum is removed with the ...

Stability of Nonlinear AR-GARCH Models [PDF]

open access: yesSSRN Electronic Journal, 2006
Abstract.  This article studies the stability of nonlinear autoregressive models with conditionally heteroskedastic errors. We consider a nonlinear autoregression of order p [AR(p)] with the conditional variance specified as a nonlinear first‐order generalized autoregressive conditional heteroskedasticity [GARCH(1,1)] model.

Some aspects of the stic system stability calculation [PDF]

open access: yesFacta Universitatis. Series: Architecture and Civil Engineering, 2009
The problem presented in this paper has been treated intensively by various researchers. However, considering that by its nature the problem of structure stability belongs to the area of nonlinear analysis, it represents an inexhaustible source for ...

On stability of standing waves of nonlinear Dirac equations

open access: yes, 2011
We consider the stability problem for standing waves of nonlinear Dirac models. Under a suitable definition of linear stability, and under some restriction on the spectrum, we prove at the same time orbital and asymptotic stability.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
