双曲流形的系统

Systoles of Hyperbolic Manifolds

Mikhail Belolipetsky, Scott A. Thomson

摘要:

证明了对每个$n\geq 2$和任何$ε>0$,存在一个紧双曲$n$ -流形,其闭测地线的长度小于$ε$ .当$ε$足够小时,这些流形是非算术的,并且它们是由Agol为$n=4$首次提出的广义近亲繁殖构造得到的。我们还表明,对于$n\geq 3$的这些流形的体积增长至少为$1/ε^{n-2}$时,$ε\to 0$。

英文摘要:

We show that for every $n\geq 2$ and any $ε>0$ there exists a compact hyperbolic $n$-manifold with a closed geodesic of length less than $ε$. When $ε$ is sufficiently small these manifolds are non-arithmetic, and they are obtained by a generalised inbreeding construction which was first suggested by Agol for $n=4$. We also show that for $n\geq 3$ the volumes of these manifolds grow at least as $1/ε^{n-2}$ when $ε\to 0$.
