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…

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…
