We present the conjecture of Lazer- McKenna, checking its validity in the one dimensional case. To obtain our results, we use essentially topological, variational and sub and supersolution methods. / Neste trabalho, estudamos questões relacionadas à existência e multiplicidade de soluções para problemas do tipo Ambrosetti-Prodi. Apresentamos a conjectura de Lazer-McKenna, verificando sua validade no caso unidimensional. Na obtenção de nosso resultados, utilizamos essencialmente métodos topológicos, variacionais e de sub e supersolução.
