Abstract

We study the elliptic boundary-value problem ∆u + g(x, u) = p(x) in Ω u|∂Ω = constant, ∫∂Ω ∂u/∂v = 0, where g is T-periodic in u, and Ω ⊂ ℝn is a bounded domain. We prove the existence of a solution under a condition on the average of the forcing term p. Also, we prove the existence of a compact interval Ip ⊂ ℝ such that the problem is solvable for p̃(x) = p(x) + c if and only if c ∈ Ip.
