摘要: 该文利用不动点指数定理和Green函数的性质, 在较弱的条件下研究了四阶微分方程 奇异边值问题正解的存在性.

关键词: 四阶奇异边值问题, 正解, 不动点指数.

Abstract: By using the fixed point index theorem and the properties of Green function, the author presents the existence of positive solutions for singular boundary value problems of fourth-order differential equations. The conditions used in this paper are weaker.

Key words: Fourth-order singular boundary value problems, Positive solutions, Fixed point index.
