Global existence for wave and beam equations with double damping and a new power nonlinearity
Khaldi Said, Arioui Fatima Zahra
We consider the Cauchy problem in for wave and beam equations with frictional, viscoelastic damping, and a new power nonlinearity. In addition to the solution and…
A new gap in the critical exponent for semi-linear structurally damped evolution equations
Khaldi Said, Arioui Fatima Zahra, Hakem Ali
Our aim in this paper is to discuss the critical exponent in semi-linear structurally damped wave and beam equations with additional dispersion term. The special model we have in m…
A note on evolution equations with modified Hartree Nonlinearity
Khaldi Said
We introduce a mathematical model in for evolution equations with modified generalized Hartree nonlinearity given by One can see tha…
Global existence for damped -evolution equations with nonlocal nonlinearity
Khaldi Said
In this research, we would like to study the global (in time) existence of small data solutions to the following damped -evolution equations with nonlocal (in space) nonlinearit…
Pitt inequality for the linear structurally damped -evolution equations
Khaldi Said
This work is devoted to improve the time decay estimates for the solution and some of its derivatives of the linear structurally damped -evolution equations. The Pitt inequality…
On generalized damped Klein-Gordon equation with nonlinear memory
Khaldi Said, Menad Mohamed
In this paper we consider the Cauchy problem for linear dissipative generalized Klein-Gordon equations with nonlinear memory in the right hand side. Our goal is to study the effect…
Effect of different additional regularity on semi-linear damped -evolution models
Khaldi Said, Arioui Fatima Zahra
The motivation of the present study is to discuss the global (in time) existence of small data solutions to the following semi-linear structurally damped -evolution models: \beg…
