Existence of large solutions for a semilinear elliptic problem via explosive sub- supersolutions

open access: yesElectronic Journal of Differential Equations, 2006
We consider the boundary blow-up nonlinear elliptic problems $Delta upmlambda | abla u|^q=k(x)g(u)$ in a bounded domain with boundary condition $u|_{partial Omega}=+infty$, where $qin [0, 2]$ and $lambdageq0$. Under suitable growth assumptions on $k$

A sub-supersolution approach for a quasilinear Kirchhoff equation [PDF]

open access: yesJournal of Mathematical Physics, 2015
In this paper, we establish an existence result for a quasilinear Kirchhoff equation, via a sub- and supersolution approach, by using the Minty-Browder’s Theorem for pseudomonotone operators theory.

The sub-supersolution method for weak solutions [PDF]

open access: yesProceedings of the American Mathematical Society, 2008
Summary: We extend the method of sub- and supersolutions in order to prove existence of \(L^1\)-solutions of the equation \(-\Delta u = f(x,u)\) in \(\Omega\), where \(f\) is a Carathéodory function. The proof is based on the Schauder's fixed point theorem.

A Sub-Supersolution Approach for Robin Boundary Value Problems with Full Gradient Dependence [PDF]

open access: yesMathematics, 2020
The paper investigates a nonlinear elliptic problem with a Robin boundary condition, which exhibits a convection term with full dependence on the solution and its gradient. A sub- supersolution approach is developed for this type of problems. The main result establishes the existence of a solution enclosed in the ordered interval formed by a sub ...

The sub-supersolution method for a nonhomogeneous elliptic equation involving Lebesgue generalized spaces [PDF]

open access: yesBoundary Value Problems, 2021
AbstractIn this paper, a nonhomogeneous elliptic equation of the form$$\begin{aligned}& - \mathcal{A}\bigl(x, \vert u \vert _{L^{r(x)}}\bigr) \operatorname{div}\bigl(a\bigl( \vert \nabla u \vert ^{p(x)}\bigr) \vert \nabla u \vert ^{p(x)-2} \nabla u\bigr) \\& \quad =f(x, u) \vert \nabla u \vert ^{\alpha (x)}_{L^{q(x)}}+g(x, u) \vert \nabla u ...

Existence of solution for a class of nonlocal elliptic problem via sub–supersolution method [PDF]

open access: yesNonlinear Analysis: Real World Applications, 2015
We show the existence of solution for some classes of nonlocal problems. Our proof combines the presence of sub and supersolution with the pseudomonotone operators theory.

On the sub-supersolution principle for p(x)-Laplacian equations

open access: yesGulf Journal of Mathematics, 2018
This paper deals with the sub-supersolution method for the p(x) -Laplacian Dirichlet problem. A sub-supersolution principle for the Dirichlet problems involving the p(x)-Laplacian is established by using induction method.
