摘要
The paper is concerned with the existence of positive solutions for the nonlinear eigenvalue problem with singularity and the superlinear sernipositone problem of second-order delay differential equations. The main results in this paper extend some of the existing literature. The proofs are based on a fixed-point theorem in cones. (c) 2005 Elsevier Ltd. All rights reserved.
