Existence of non-negative solutions for semilinear elliptic systems via variational methods

open access: yesNonlinear Analysis, 2012
In this paper we consider a semilinear elliptic system with nonlinearities, indefinite weight functions and critical growth terms in bounded domains. The existence result of nontrivial nonnegative solutions is obtained by variational methods.

Multiple solutions for a class of nonlocal quasilinear elliptic systems in Orlicz–Sobolev spaces

open access: yesBoundary Value Problems, 2021
In this paper, we study some results on the existence and multiplicity of solutions for a class of nonlocal quasilinear elliptic systems. In fact, we prove the existence of precise intervals of positive parameters such that the problem admits multiple ...

Three solutions for fractional elliptic systems involving ψ-Hilfer operator

open access: yesBoundary Value Problems
In this paper, using variational methods introduced in the previous study on fractional elliptic systems, we prove the existence of at least three weak solutions for an elliptic nonlinear system with a p-Laplacian ψ-Hilfer operator.

Nonlinear elliptic systems [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2000
In this paper we treat the question of the existence of solutions of boundary value problems for systems of nonlinear elliptic equations of the form - deltau = f (x, u, v,Ñu,Ñv), - deltav = g(x, u, v, Ñu, Ñv), in omega, We discuss several classes of such

Elliptic methods for solving the linearized field equations of causal variational principles [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2021
The existence theory is developed for solutions of the inhomogeneous linearized field equations for causal variational principles. These equations are formulated weakly with an integral operator which is shown to be bounded and symmetric on a Hilbert ...

A variational method for solving quasilinear elliptic systems involving symmetric multi-polar potentials [PDF]

open access: yesDifferential Equations & Applications, 2020
Summary: In this paper, a system of quasilinear elliptic equations is investigated, which involves multiple critical Hardy-Sobolev exponents and symmetric multi-polar potentials. By employing the variational methods and analytic techniques, the relevant best constants are studied and the existence of \((\mathbb{Z}_k \times\mathbb{SO}(N-2))^2 ...

A priori bounds and positive solutions for non-variational fractional elliptic systems [PDF]

open access: yesDifferential and Integral Equations, 2014
In this paper we study strongly coupled elliptic systems in non-variational form involving fractional Laplace operators. We prove Liouville type theorems and, by mean of the blow-up method, we establish a priori bounds of positive solutions for ...
