关于正曲Finsler球面上闭测地线的平均指数

On the average indices of closed geodesics on positively curved Finsler spheres

Wei Wang

摘要:

本文证明了:在任意Finsler $n$ -球面$(S^n, F)$上,对于$n\ge 6$,如果可逆性$λ$和旗曲率$K$满足$(\fracλ{λ+1})^2<K\le 1$,则存在无穷多条素闭测地线,或者存在具有无理平均指数的$[\frac{n}{2}]-2$闭测地线.如果度量是不平坦的,则当闭测地线的个数有限时,存在具有无理平均指数的$n-3$闭测地线.

英文摘要:

In this paper, we prove that on every Finsler $n$-sphere $(S^n, F)$ for $n\ge 6$ with reversibility $λ$ and flag curvature $K$ satisfying $(\fracλ{λ+1})^2<K\le 1$, either there exist infinitely many prime closed geodesics or there exist $[\frac{n}{2}]-2$ closed geodesics possessing irrational average indices. If in addition the metric is bumpy, then there exist $n-3$ closed geodesics possessing irrational average indices provided the number of closed geodesics is finite.
