In this paper we investigate numerically positive solution of the equation - Δ u = λ f (x, u) + μ g (x, u) with Dirichlet boundary condition in a boundary domain Ω for λ > 0, μ ∈ R. We will show that in which range of λ, this problem achieves a numerical solution. © 2007 Elsevier Inc. All rights reserved.
