摘要
本文利用上下解方法和不动点理论给出了负指数ＥｍｄｅｎＦｏｗｌｅｒ方程奇异边值问题有Ｃ［０，１］和Ｃ１［０，１］正解存在的充分必要条件．
This paper investigates the existence of positive solutions of singular boundary value problems of negative exponent Emden Fowler equations. A necessary and sufficient condition for the existence of C positive solutions as well as C 1 positive solutions is given by means of the method of lower and upper solutions with the fixed point theorems.
