摘要：

We study the existence of positive solutions of the periodic, Neumann or Dirichlet problem for the semilinear equation u" + f (t, u) = 0, 0 less-than-or-equal-to t less-than-or-equal-to T, where f is a Caratheodory function. Our assumptions in each case are such that the problem possesses a lower solution or an upper solution.
