一类奇异Dirichlet边值问题的正解

Positive Solutions of a Class of Singular Dirichlet Boundary Value Problems

在对f(u)没有超(次)线性的限制下,通过构造一个特殊的锥,利用逼近方法及不动点指数理论得到了一类奇异二阶边值问题的C^1[0,1]正解。

This paper studies the existence of positive solutions for a class of seoond-order Singular boundary value problem whose nonlinear term has not the restriction of superlinear(or sublinear)by constructing a special cone,using approximation method and fixed point index theorem
