Neste trabalho pesquisamos a ordem de convergência atingível da aproximação num certo espaço polinomial spline para a solução de equações integrais de Volterra de segunda espécie com núcleo regular e fracamente singular. Se considerarmos equações de Volterra com núcleo regular, a suavidade da solução é determinada pela suavidade do núcleo dado e pela função forçante. Isto,por sua vez, implica que a aproximação por colocação exibe ordem ótima de convergência global. Superconvergência local é atingível para alguma escolha apropriada dos parâmetros de colocação. Entretanto, se admitirmos núcleos contendo singularidades fracas do tipo algébrico, e se empregarmos uma sequência de malhas quase-uniforme, então a ordem de convergência global da apr...
