Laguerre and Hermite Collocation Methods for Unbounded Domains

open access: yesEast Asian Journal on Applied Mathematics, 2018
We discuss spectral collocation methods based on Jacobi-Gauss-Lobatto points and Laguerre and Hermite collocation for unbounded domains. These methods are well conditioned, and some numerical experiments demonstrate quite high accuracy.

On global solution, energy decay and blow-up for 2-D Kirchhoff equation with exponential terms

open access: yesBoundary Value Problems, 2014
This paper is concerned with the study of damped wave equation of Kirchhoff type utt−M(∥∇u(t)∥22)△u+ut=g(u) in Ω×(0,∞), with initial and Dirichlet boundary condition, where Ω is a bounded domain of R2 having a smooth boundary ∂ Ω.

General decay for a system of nonlinear viscoelastic wave equations with weak damping

open access: yesBoundary Value Problems, 2012
In this paper, we are concerned with a system of nonlinear viscoelastic wave equations with initial and Dirichlet boundary conditions in Rn (n=1,2,3). Under suitable assumptions, we establish a general decay result by multiplier techniques, which extends

Global existence of a coupled Euler-Bernoulli plate system with variable coefficients

open access: yesBoundary Value Problems, 2014
In this paper, we study the initial boundary value problem of a coupled Euler-Bernoulli plate system with spatially varying coefficients of viscosity, damping and source term in a bounded domain.

Instability and stability properties of traveling waves for the double dispersion equation [PDF]

open access: yes, 2002
In this article we are concerned with the instability and stability properties of traveling wave solutions of the double dispersion equation $~u_{tt} -u_{xx}+a u_{xxxx}-bu_{xxtt} = - (|u|^{p-1}u)_{xx}~$ for $~p>1$, $~a\geq b>0$.

Global existence and energy decay of solutions to the Cauchy problem for a wave equation with a weakly nonlinear dissipation

open access: yesAbstract and Applied Analysis, Volume 2004, Issue 11, Page 935-955, 2004., 2004
We prove the global existence and study decay properties of the solutions to the wave equation with a weak nonlinear dissipative term by constructing a stable set in H1(ℝn).

Weak solutions for the singular potential wave system

open access: yesBoundary Value Problems, 2014
We investigate the existence of weak solutions for a class of the system of wave equations with singular potential nonlinearity. We obtain a theorem which shows the existence of nontrivial weak solution for a class of the wave system with singular ...

Blowup of solutions with positive energy in nonlinear thermoelasticity with second sound

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 3, Page 201-211, 2004., 2004
This work is concerned with a semilinear thermoelastic system, where the heat flux is given by Cattaneo′s law instead of the usual Fourier′s law. We will improve our earlier result by showing that the blowup can be obtained for solutions with “relatively” positive initial energy.

Decay rates for solutions of a Timoshenko system with a memory condition at the boundary

open access: yesAbstract and Applied Analysis, Volume 7, Issue 10, Page 531-546, 2002., 2002
We consider a Timoshenko system with memory condition at the boundary and we study the asymptotic behavior of the corresponding solutions. We prove that the energy decay with the same rate of decay of the relaxation functions, that is, the energy decays exponentially when the relaxation functions decays exponentially and polynomially when the ...
