摘要
In this paper, the existence of multiple positive solutions for singular Sturm-Liouville boundary value problems on the half-line is investigated. By applying the fixed point index theorem of cone map, some existence and multiplicity results of positive solutions are derived. Our results improve and generalize many well-known results. Two examples are presented to demonstrate the application of our main results. (c) 2009 Elsevier Ltd. All rights reserved.
