Existence and uniqueness of the weak solution for Keller-Segel model coupled with Boussinesq equations

Autor: Slimani Ali, Bouzettouta Lamine, Guesmia Amar

Publikováno v: Demonstratio Mathematica, Vol 54, Iss 1, Pp 558-575 (2021)

Keller-Segel chemotaxis model is described by a system of nonlinear partial differential equations: a convection diffusion equation for the cell density coupled with a reaction-diffusion equation for chemoattractant concentration. In this work, we st

Blow up at finite time for wave equation in visco-elasticity: a new kind for one spatial variable Emden-Fowler type

Autor: Laouar, Lakhdar Kassah, Zennir, Khaled, Guesmia, Amar

For one spatial variable, a new kind of nonlinear wave equation for Emden-Fowler type is considered with boundary value null and initial values. Under certain conditions on the initial data and the exponent p, we exhibit that the visco-elastic term l

Well-posedness and energy decay of swelling porous elastic soils with a second sound and delay term

Autor: Abdelli Manel, Lamine Bouzettouta, Guesmia Amar, Baibeche Sabah

In this paper we consider a one-dimensional swelling porous-elastic system with second sound and delay term acting on the porous equation. Under suitable assumptions on the weight of delay, we establish the well-posedness of the system by using semig

Energy Decay of Damped System of Wave Equations in IR^n via Fourier Transform

Autor: ZENNİR, Khaled, L. LAKHDAR, Kassah, BOULAARAS, Saleh, GUESMİA, Amar

Publikováno v: Volume: 1, Issue: 2 68-76
Mathematical Advances in Pure and Applied Sciences

The wave equation with fading memory, in bounded domain, has been deeply studied by several authors. Here, we establish a decay results for a class of weak-viscoelastic wavesystem in IR^n. We are going to construct an appropriate Lyapunov function as
