Introduction and notations. Let Ω be a bounded region in Rn. In this note we discuss the existence of weak solutions (see [4, Section 2]) of the Dirichlet problem

(I)

where Δ is the Laplacian operator, g : Ω × RR and f : Ω × Rn+1R are functions satisfying the Caratheodory condition (see [2, Section 3]), and ∇ is the gradient operator.

We let λ1 < λ2 ≦ … ≦ λm ≦ … denote the sequence of numbers for which the problem

(II)

has nontrivial weak solutions.
