introduction/brief CV
I'm Zaid Hajjej assistant professor of Mathematics at King Saud University since January 2020. My research focuses on the study of assymptotic behavior (stability) of some PDEs (wave, suspension bridge, Kirchhoof plate, etc).
areas of expertise
Stability of PDEs, Functional Analysis, Operator Theory.

In this paper, a weakly coupled system (by the displacement of symmetric type) consisting of a viscoelastic Kirchhoff plate equation involving free boundary conditions and the viscoelastic wave…
In this manuscript we consider a coupled, by second order terms, system of two wave
equations with a past history acting on the first equation as a stabilizer. We show that the solution of…
In this paper, a system of coupled quasi-linear and linear wave equations with a finite memory term is concerned. By constructing an appropriate Lyapunov function, we prove that the total energy…
