AbstractLet Ω be a bounded domain in Rn (n ⩾ 2) with smooth boundary ∂Ω. We discuss the existence and multiplicity of solutions of the boundary value problem −Δu = p(x, u) in Ω, u = 0 on ∂Ω, roughly speaking, under the assumption that λl ⩽ limt → ± ∞(p(x, t)t) ⩽ λl + 1 for two distinct consecutive eigenvalues λl, λl + 1 of the first boundary value problem of −Δ
