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…

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…
