Existence of Weak Solutions for a Nonuniformly Elliptic Nonlinear System in R
نویسنده
چکیده
We study the nonuniformly elliptic, nonlinear system − div(h1(x)∇u) + a(x)u = f(x, u, v) in R , − div(h2(x)∇v) + b(x)v = g(x, u, v) in R . Under growth and regularity conditions on the nonlinearities f and g, we obtain weak solutions in a subspace of the Sobolev space H1(RN , R2) by applying a variant of the Mountain Pass Theorem.

Existence of at least three weak solutions for a quasilinear elliptic system
In this paper, applying two theorems of Ricceri and Bonanno, we will establish the existence of three weak solutions for a quasilinear elliptic system. Indeed, we will assign a differentiable nonlinear operator to a differential equation system such that the critical points of this operator are weak solutions of the system. In this paper, applying two theorems of R...
متن کاملExistence and multiplicity of positive solutions for a class of semilinear elliptic system with nonlinear boundary conditions
This study concerns the existence and multiplicity of positive weak solutions for a class of semilinear elliptic systems with nonlinear boundary conditions. Our results is depending on the local minimization method on the Nehari manifold and some variational techniques. Also, by using Mountain Pass Lemma, we establish the existence of at least one solution with positive energy.
