通过构造一个特殊的锥,利用范数形式的锥拉伸不动点定理,研究了一类二阶奇异半正Sturm liouville边值问题,得到了其Cp1[0,1]正解存在的一个判定方法.
The paper studies a class of singular semipositone second order Sturm-liouville boundary value problems by using fixed point theorem of cone expansion of norm type. A new result on the existence of Cp^1[0,1] positive solutions for the question is obtained.
