摘要
本文基于锥拉伸和锥压缩不动点定理,得到一类三阶时滞奇异边值问题至少具有两个正解的充分条件,并给出例子说明定理的应用.
Based on the fixed-point theorem of cone expansion and compression, some sufficient conditions for the existence of at least two positive solutions for a singular third-order boundary val- ue problem（BVP） with delay are derived. An example is given to illustrate our results.
