T. Godoy, Uriel Kaufmann, S. Paczka · 2011
Abstract. Let Ω ⊂ RN be a smooth bounded domain, let a, b be two bounded nonnegative T-periodic functions, and let 0 0 is a real parameter. We also analyze the behaviour of the solutions with respect to λ. All results remain true for the corresponding elliptic problems. 1.
