In this paper, we prove the existence of a nonnegative solution to nonlinear parabolic
problems with two absorption terms and a singular lower order term. More precisely, we …

We study the regularizing effect of two lower order terms to nonlinear Dirichlet problems with
singularity. The simplest example model is-div a (x)+| u| q|∇ u| p-2∇ u+ us= fu θ in Ω u> 0 in …

In this paper, we study a class of nonlinear elliptic problems whose model is the following-
div (b (u)|∇ u| p-2∇ u)= f (1+ 1| u| γ) in Ω, u= 0 on∂ Ω, where Ω is a bounded open subset …

In this article, we deal with a class of nonlinear degenerate elliptic equations involving
singular nonlinearities of the form-div|∇ u| p-2∇ u (1+ u) λ+|∇ u| pu θ= fu γ in Ω, u> 0 in Ω …

In this paper, we study the existence and the summability of solutions to a Robin boundary
value problem whose prototype is the following: $$\begin {cases}-\text {div}(b (| u|)\nabla u) …

This thesis is devoted to the study of some parabolic partial differential equations (PDEs)
involving absorption term or singular natural growth or Hardy potential and singular lower …

This thesis concerns the study of some elliptic, nonlinear singular problems. In the model
problems considered in this work, we place ourselves on a bounded domain Ω of RN, with …
