چکیده
In [] Rammaha and Sakuntasathien studied the global well posedness of the solution of problem (.). Agre and Rammaha [] studied the global existence and the blow up of the solution of problem (.) for k = l = θ = = , and also Alves et al. [] investigated the existence, uniform decay rates and blow up of the solution to systems. After that, the blow up result was improved by Houari []. Also, Houari [] showed that the local solution obtained in [] is global and decay of solutions. When k = l = θ = = , equation (.) reduces to the following form:

Global existence, decay and blow up solutions for coupled nonlinear wave equations with damping and source terms
We study the initial-boundary value problem for a system of nonlinear wave equations with nonlinear damping and source terms, in a bounded domain. The decay estimates of the energy function are established by using Nakao’s inequality. The nonexistence of global solutions is discussed under some conditions on the given parameters.
متن کاملBlow-up of Solutions to a Coupled Quasilinear Viscoelastic Wave System with Nonlinear Damping and Source
We study the blow-up of the solution to a quasilinear viscoelastic wave system coupled by nonlinear sources. The system is of homogeneous Dirichlet boundary condition. The nonlinear damping and source are added to the equations. We assume that the relaxation functions are non-negative non-increasing functions and the initial energy is negative. The competition relations among the nonlinear prin...

*Correspondence: [email protected] School of Mathematical Sciences, Ocean University of China, Qingdao, P.R. China Abstract This work is concerned with the Dirichlet initial boundary problem for a semilinear viscoelastic wave system with nonlinear weak damping and source terms. For nonincreasing positive functions g and h, we show the finite time blow-up of some solutions whose initial data hav...
متن کاملControl and Cybernetics Existence and Uniqueness of Solutions to Wave Equations with Nonlinear Degenerate Damping and Source Terms
Abstract: In this article we focus on the global well-posedness of the differential equation utt−∆u+|u|kj′(ut) = |u|p−1 u in Ω×(0, T ), where j′ denotes the derivative of a C convex and real valued function j. The interaction between degenerate damping and a source term constitutes the main challenge of the problem. Problems with non-degenerate damping (k = 0) have been studied in the literatur...

This article concerns the blow-up and asymptotic stability of weak solutions to the wave equation utt −∆u + |u|j(ut) = |u|p−1u in Ω× (0, T ), where p > 1 and j′ denotes the derivative of a C1 convex and real value function j. We prove that every weak solution is asymptotically stability, for every m such that 0 < m < 1, p < k + m and the the initial energy is small; the solutions blows up in fi...
