非共振奇异超线性边值问题正解存在的充分必要条件
A NECESSARY AND SUFFICIENT CONDIDTION FOR EXISTENCE OF POSITIVE SOLUTIONS TO SINGULAR SUPERLINEAR BOUNDARY VALUE PROBLEMS AT NONRESONANCE
【摘要】 本文研究非共振奇异超线性边值问题正解的存在性,利用锥上的不动点定理给出了非共振奇异超线性边值问题有C1[0,1]正解存在的充分必要条件.
【Abstract】 This paper studies the existence of positive solutions to the singular superlinear second order boundary value problem at nonresonance. A necessary and sufficient conditon for the existence of positive solutions in C1 [0,1] is given by means of the fixed point theorem on cones.
