Title: Positive solutions for a class of singular boundary-value problems Author: Dang Dinh Hai (Mississippi State Univ., MS, USA) Abstract: This 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. Submitted August 25, 2005. Published January 26, 2006.
