研究n阶时滞微分方程的非线性特征值问题以及超线性的Semipositone问题,推广了以往的结果.主要结果的证明应用了Guo-Krasnoselskii不动点定理.
This paper dealt with the existence of positive solutions for the nonlinear eigenvalue problem and the superlinear semipositone problem of an nth-order delay differential equation. The main results in this paper generalize some of the existing results in the literature. The proofs are based on the well-known Guo-Krasnoselskii fixed-point theorem.
