摘要: 研究一类具有SturmLiouville边值条件的半线性半正奇异边值问题. 利用分析技巧, 对所讨论问题做了一系列的估计, 进而利用不动点指数理论和ArzelaAscoli定理, 得到了这类问题至少存在一个正解的充分条件.

关键词: 奇异边值问题, 正解, 半正问题

Abstract: The authors studied a class of semilinear semipositone singular SturmLiouville boundary value problems. A sufficient condition for the existence of a positive solution was obtained with carefully analyzing of the equation. The arguments are based upon the fixed point index theory and ArzelaAscoli theorem.

Key words: singular boundary value problem, positive solutions, semipositone
