摘要：
This article concerns the existence and multiplicity of positive solutions for the singular Sturm-Liouville boundary value problem (p(t)u'(t))' + h(t)f(t, u(t)) = 0, 0 < t < infinity, au(0) - b lim(t -> 0+) p(t)u'(t) = 0, c lim(t ->infinity) u(t) + d lim(t ->infinity) p(t)u'(t) = 0. We use fixed point index theory to establish our main results based on a priori estimates derived by utilizing spectral properties of associated linear integral operators.
