四维流形中最短闭测地线的长度

Length of a shortest closed geodesic in manifolds of dimension four

Nan Wu, Zhifei Zhu

摘要:

本文证明了对于任意具有里奇曲率$|Ric|\leq 3$,体积$vol(M)>v>0$和直径$diam(M)<D$的闭四维单连通黎曼流形$M$,最短闭测地线的长度由一个仅依赖于$v$和$D$的函数$F(v,D)$有界.我们的结果的证明是基于最近由J.Cheeger和A.纳伯

英文摘要:

In this paper, we show that for any closed 4-dimensional simply-connected Riemannian manifold $M$ with Ricci curvature $|Ric|\leq 3$, volume $vol(M)>v>0$, and diameter $diam(M)<D$, the length of a shortest closed geodesic is bounded by a function $F(v,D)$ which only depends on $v$ and $D$. The proofs of our result are based on a recent theorem of diffeomorphism finiteness of the manifolds satisfying the above conditions proven by J. Cheeger and A. Naber.
