Original Abstract

We study the existence and multiplicity of positive solutions to the periodic problem u '' = p(t)u - q(t, u)u + f(t); u(0) = u(omega), u'(0) = u'(omega), where p, f is an element of L([0, omega]) and q: [0, omega] x R -> R is a Caratheodory function. By using the method of lower and upper functions, we show some properties of the solution set of the considered problem and, in particular, the existence of a minimal positive solution.
