Global existence and dynamic structure of solutions for damped wave equation involving the fractional Laplacian

open access: yesDemonstratio Mathematica, 2021
We consider strong damped wave equation involving the fractional Laplacian with nonlinear source. The results of global solution under necessary conditions on the critical exponent are established.

On global existence and nonexistence of solutions to a quasi-linear wave equation with memory, nonlinear damping and source terms

open access: yesScientific African, 2021
In this paper, we consider a quasi-linear wave equation with memory, nonlinear source and damping termsutt−Δut−∑i=1n∂∂xiσi(uxi)+∫0tm(t−s)Δuds+f(ut)=g(u).Under some polynomial growth conditions on the nonlinear functions σi(i=1,2,…,n),  f and g, we obtain

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 $~p>1$, $~a\geq b>0$.

Ulam-Hyers stability of a parabolic partial differential equation

open access: yesDemonstratio Mathematica, 2019
The goal of this paper is to give an Ulam-Hyers stability result for a parabolic partial differential equation. Here we present two types of Ulam stability: Ulam-Hyers stability and generalized Ulam-Hyers-Rassias stability.

General decay of the solution for a viscoelastic wave equation with a time-varying delay term in the internal feedback

open access: yes, 2012
In this paper we consider a viscoelastic wave equation with a time-varying delay term, the coefficient of which is not necessarily positive. By introducing suitable energy and Lyapunov functionals, under suitable assumptions, we establish a general ...
