Nonlinear finite elements: Sub- and supersolutions for the heterogeneous logistic equation

open access: yesJournal of Differential Equations, 2021
In this paper we give the necessary and sufficient conditions for the Discrete Maximum Principle (DMP) to hold. We prove the convergence of the nonlinear finite element method applied to the logistic equation by using that the Jacobian matrix evaluated in the supersolution, provided by the a priori bound, is a non-singular M-matrix, which is proved in ...

Upper and lower absolutely continuous functions with applications to discontinuous differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
We use upper and lower absolutely continuous functions as subsolutions and supersolutions to discontinuous ordinary differential equations. We present sufficient conditions for the existence of extremal solutions to initial value problems. Due to a new

Discontinuous Variational-Hemivariational Inequalities Involving the p-Laplacian

open access: yesJournal of Inequalities and Applications, 2007
We deal with discontinuous quasilinear elliptic variational-hemivariational inequalities. By using the method of sub- and supersolutions and based on the results of S. Carl, we extend the theory for discontinuous problems.

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.

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 ...
