R satisfies some convenient conditions and h 2 H--1(. / Neste trabalho, estudamos um teorema de ponto fixo para operadores crescentes em espaços vetoriais ordenados e o aplicamos para obter resultados de existência de solução fraca para problemas elípticos semilineares do tipo 8<: ---u = f(x; u) + h; em u = 0; sobre @ em que - RN é um domínio suave, f : - R ! R satisfaz algumas condições convenientes e h 2 H- -1(:).
