Abstract

Variational methods are used to prove the multiplicity of positive solutions for the following singular elliptic equation:

where 0 ∈ Ω ⊂ ℝN, N ≥ 3, is a bounded domain with smooth boundary ∂ Ω, λ > 0 , , 0 ≤ s < 2, 2*(s)=2(Ns)/(N−2) and f and g are continuous functions on , that change sign on Ω.
