摘 要: | 应用锥不动点定理并结合格林函数的性质,讨论了一类带积分边界条件的奇异梁方程多个正解的存在性问题。与以往关于梁方程获得1个或2个正解的结论不同,这里使用Leggett-Williams不动点定理得到了3个正解的存在性结果。 |
关 键 词: | 常微分方程;积分边界条件;奇异梁方程;Leggett-Williams不动点定理;3个正解 |

Abstract: | Using fixed point theorem on cones together with the properties of Green function, the multiplicity of positive solutions for a singular beam equation with integral boundary conditions is considered. Here, we obtain three positive solutions by applying Leggett-Williams’ fixed point theorem, which is different from that one or two positive solutions of beam equations in the existing literature. |
Key words: | ordinary differential equation; integral boundary condition; singular beam equation; Leggett-Williams’ fixed point theorem; triple positive solutions |
