本文研究了常微分方程$$\begin{equation*} u^{\prime\prime}+u=\frac{f}{u^3} \ \textrm{ in } \mathbb{R} \end{equation*}$$中正周期解的存在性,其中 是正周期光滑函数。借助新的广义 Blaschke-Santaló 不等式,我们得到了新的解的存在性结果。
In this paper the existence of positive-periodic solutions to the ordinary differential equation $$\begin{equation*} u^{\prime\prime}+u=\frac{f}{u^3} \ \textrm{ in } \mathbb{R} \end{equation*}$$is studied, whereis a positive-periodic smooth function. By virtue of a new generalized Blaschke–Santaló inequality, we obtain a new existence result of solutions.
