A Class of Non-linear Anisotropic Elliptic problems with Unbounded Coefficients and Singular Quadratic Lower Order Terms
Fessel Achhoud, Hichem Khelifi
In this work, we study the existence and regularity results of anisotropic elliptic equations with a singular lower order term that grows naturally with respect to the gradient and…
Parabolic problems with slightly superlinear convection terms
Fessel Achhoud
In this paper we deal with a non-linear parabolic problem which involving a convection term with super--linear growth, whose model is \[ \frac{\partial u}{\partial t}-÷(\mathcal{M…
Anisotropic elliptic equations involving unbounded coefficients and singular nonlinearities
Fessel achhoud, Hichem Khelifi
In this paper, we study the existence and regularity of solutions for a class of nonlinear singular elliptic equations involving unbounded coefficients and a singular right-hand si…
The influence of the Hardy potential and a Convection Term on a Nonlinear Degenerate Elliptic Equations
Fessel Achhoud, Abdelkader Bouajaja, Hicham Redwane
This paper is devoted to prove existence of renormalized solutions for a class of non--linear degenerate elliptic equations involving a non--linear convection term, which satisfies…
The effect of Q-condition in elliptic equations involving Hardy potential and singular convection term
Fessel Achhoud, Abdelkader Bouajaja, Hicham Redwane
Using an approach by contradiction we prove the existence and uniqueness of a weak solution to a quasi-linear elliptic boundary value problem with singular convection term and Hard…
