On the Hénon equation: Asymptotic profile of ground states, II

Journal of Differential Equations, 2005
This paper is concerned with the qualitative property of the ground state solutions for the Hénon equation. By studying a limiting equation on the upper half space \mathbf{R}_{ + }^{N} , we investigate the asymptotic energy and the asymptotic profile of the ground states for the Hénon ...

Stability of Non-Isolated Asymptotic Profiles for Fast Diffusion [PDF]

Communications in Mathematical Physics, 2016
The stability of asymptotic profiles of solutions to the Cauchy-Dirichlet problem for Fast Diffusion Equation (FDE, for short) is discussed. The main result of the present paper is the stability of any asymptotic profiles of least energy. It is noteworthy that this result can cover non-isolated profiles, e.g., those for thin annular domain cases.

Asymptotic profiles of solutions to viscous Hamilton–Jacobi equations

Journal de Mathématiques Pures et Appliquées, 2004
The large time behavior of solutions to Cauchy problem for viscous Hamilton-Jacobi equation is classified. The large time asymptotics are given by very singular self-similar solutions on one hand and by self-similar viscosity solutions on the other ...

Existence and asymptotic stability of relaxation discrete shock profiles [PDF]

Mathematics of Computation, 2004
The author studies the asymptotic nonlinear stability of discrete shocks by means of the relaxation schemes for one-dimensional systems of hyperbolic conservation laws. The existence of discrete shocks is proven. Further, it is proven that weak single discrete shocks are nonlinearly stable in \(L^2\). The results are obtained by using the weighted norm

Entanglement harvesting for different gravitational wave burst profiles with and without memory

Journal of High Energy Physics, 2023
In the present article, we study how different gravitational wave (GW) burst profiles in linearized gravity, with and without the asymptotic memory, may influence the harvesting between two static Unruh-DeWitt detectors.

Numerical solution of the Burgers equation associated with the phenomena of longitudinal dispersion depending on time

Heliyon, 2022
In this study, the Burgers equation governing the time-dependent dispersion phenomena is solved numerically using the finite difference scheme and the Runge-Kutta 4 algorithm with appropriate initial and boundary conditions. Two time-dependent dispersion

On the dynamics of a diffusive SEIRS epidemic model

European Journal of Applied Mathematics
This work investigates the dynamics of positive classical solutions to a diffusive susceptible-exposed-infected-recovered-susceptible epidemic model with a mass-action incidence mechanism in spatially heterogeneous environments. Under minimal assumptions

Heat transfer analysis of GO-water nanofluid flow between two parallel disks

Propulsion and Power Research, 2015
In this paper, the unsteady magnetohydrodynamic (MHD) squeezing flow between two parallel disks (which is filled with nanofluid) is considered. The Galerkin optimal homotopy asymptotic method (GOHAM) is used to obtain the solution of the governing ...

Spectral methods for internal waves: indistinguishable density profiles and double-humped solitary waves [PDF]

Nonlinear Processes in Geophysics, 2011
Internal solitary waves are widely observed in both the oceans and large lakes. They can be described by a variety of mathematical theories, covering the full spectrum from first order asymptotic theory (i.e.
