摘要:

利用不动点指数理论研究了一类含p-Laplacian算子三点四阶奇异边值问题正解的存在性,给出了至少存在两个正解的条件,改进并推广了最近的一些已知结果。

关键词: p-Laplacian算子, 奇异边值问题, 正解, 不动点指数

Abstract:

Abstract∶This paper employs the theory of fixed point index to investigate the existence of two positive solutions for a class of fourth-order three-point singular boundary value problems with a p-Laplacian operator. The paper also presents some sufficient conditions that at least two positive solutions exist. Our work improves some recently known results.

Key words: p-Laplacian, singular boundary value problem, positive solution, fixed point index
