Positive solutions for a class of singular boundary-value problems. <i>Electronic Journal of Differential Equations, 2006</i>(13), pp. 1-6.1072-6691https://hdl.handle.net/10877/13886This paper concerns the existence and multiplicity of positive solutions for Sturm-Liouville boundary-value problems. We use fixed point theorems and the sub-super solutions method to two solutions to the problem studied.Text6 pages1 file (.pdf)enAttribution 4.0 InternationalPositive solutionsSingularSub-super solutionsArticle
