Existence of Positive Solutions for Semilinear Elliptic Systems with Indefinite Weight
This article concerns the existence of positive solutions of semilinear elliptic system −∆u = λa(x)f(v), in Ω, −∆v = λb(x)g(u), in Ω, u = 0 = v, on ∂Ω, where Ω ⊆ RN (N ≥ 1) is a bounded domain with a smooth boundary ∂Ω and λ is a positive parameter. a, b : Ω → R are sign-changing functions. f, g : [0,∞) → R are continuous with f(0) > 0, g(0) > 0. By applying LeraySchauder fixed point theorem, w...
متن کاملMultiplicity of Positive Solutions of laplacian systems with sign-changing weight functions
In this paper, we study the multiplicity of positive solutions for the Laplacian systems with sign-changing weight functions. Using the decomposition of the Nehari manifold, we prove that an elliptic system has at least two positive solutions.

متن کاملExistence of Positive Radial Solutions for Some Nonlinear Elliptic Systems
In this paper we study a class of nonvariational elliptic systems, by using the Gidas-Spruck Blow-up method. first, we obtain a priori estimates, and then using Leray-Schauder topological degree theory, we establish the existence of positive radial solutions vanishing at infinity.
