平面上一类强迫Kepler问题的周期解

Periodic solutions to a forced Kepler problem in the plane

A. Boscaggin, W. Dambrosio, D. Papini

摘要:

给定一个光滑函数$U(t,x)$,$T$ -周期的第一个变量,并满足$U(t,x) = \mathcal{O}(\vert x \vert^α)$的一些$α\in (0,2)$作为$\vert x \vert \to \infty$,我们证明了强迫开普勒问题$$ \ddot x = - \dfrac{x}{|x|^3} + \nabla_x U(t,x),\qquad x\in {\mathbb{R}}^2, $$有一个广义$T$ -周期解,根据文章[Boscaggin,Ortega,Zhao,\emph{Periodic solutions and regularization of a Kepler problem with time-dependent perturbation},Trans. Amer. Math. Soc,2018]中给出的定义。证明依赖于变分的论点。

英文摘要:

Given a smooth function $U(t,x)$, $T$-periodic in the first variable and satisfying $U(t,x) = \mathcal{O}(\vert x \vert^α)$ for some $α\in (0,2)$ as $\vert x \vert \to \infty$, we prove that the forced Kepler problem $$ \ddot x = - \dfrac{x}{|x|^3} + \nabla_x U(t,x),\qquad x\in {\mathbb{R}}^2, $$ has a generalized $T$-periodic solution, according to the definition given in the paper [Boscaggin, Ortega, Zhao, \emph{Periodic solutions and regularization of a Kepler problem with time-dependent perturbation}, Trans. Amer. Math. Soc, 2018]. The proof relies on variational arguments.
