Finsler $n$ -球面上闭测地线的存在性

Existence of closed geodesics on Finsler $n$-spheres

Wei Wang

摘要:

本文证明了:在任何可逆性$λ$满足$F^2<(\frac{λ+1}λ)^2g_0$和$l(S^n, F)\ge π(1+\frac{1}λ)$的Finsler $n$ -球面$(S^n, F)$上,总存在至少一条不自交的$n$素闭测地线,其中$g_0$是$S^n$上常曲率为1的标准黎曼度量,$l(S^n, F)$是$(S^n, F)$上最短测地线环的长度.我们还研究了这些闭测地线的稳定性。

英文摘要:

In this paper, we prove that on every Finsler $n$-sphere $(S^n, F)$ with reversibility $λ$ satisfying $F^2<(\frac{λ+1}λ)^2g_0$ and $l(S^n, F)\ge π(1+\frac{1}λ)$, there always exist at least $n$ prime closed geodesics without self-intersections, where $g_0$ is the standard Riemannian metric on $S^n$ with constant curvature 1 and $l(S^n, F)$ is the length of a shortest geodesic loop on $(S^n, F)$. We also study the stability of these closed geodesics.
