Asymptotic approach for the rigid condition of appearance of the oscillations in the solution of the Painleve-2 equation [PDF]
arXiv, 1999 The asymptotic solution for the Painleve-2 equation with small parameter is considered. The solution has algebraic behavior before point $t_*$ and fast oscillating behavior after the point $t_*$. In the transition layer the behavior of the asymptotic solution is more complicated. The leading term of the asymptotics satisfies the Painleve-1 equation and

Asymptotic Properties of Difference Equations for Isotropic Loop Quantum Cosmology
, 2005 In loop quantum cosmology, a difference equation for the wave function describes the evolution of a universe model. This is different from the differential equations that arise in Wheeler-DeWitt quantizations, and some aspects of general properties of ...

Asymptotic behavior for a quadratic nonlinear Schrodinger equation
Electronic Journal of Differential Equations, 2008 We study the initial-value problem for the quadratic nonlinear Schrodinger equation $$displaylines{ iu_{t}+frac{1}{2}u_{xx}=partial _{x}overline{u}^{2},quad xin mathbb{R},; t>1, cr u(1,x)=u_{1}(x),quad xin mathbb{R}. }$$ For small initial data $u_{

Slowly decaying tails of massive scalar fields in spherically symmetric spacetimes [PDF]
, 2001 We study the dominant late-time behaviors of massive scalar fields in static and spherically symmetric spacetimes. Considering the field evolution in the far zone where the gravitational field is weak, we show under which conditions the massive field ...

Asymptotic behavior of a weakly forced dry friction oscillator [PDF]
, 2007 This note is devoted to stick-slip aspects of the motion of a dry friction damped oscillator under weak irregular forcing. Our main result complements[10, Theorem 3.(a)] and is also related to [1], where a non-Lipschitz model for Coulomb friction was consider in the unforced case. We provide sufficient conditions guaranteeing that solutions stabilizing

Chemistry–Methods, EarlyView.This work explores data acquisition and reduction protocols for atomic pair distribution scheme that enhances high‐angle data collection, and the effects of instrumental parameters on resulting pair distribution functions are examined. A correction for sample absorption in PDFgetX3 is introduced. Herein, data acquisition protocols are explored and data
