凸余紧双曲流形上的波0迹和长度谱

Wave 0-Trace and length spectrum on convex co-compact hyperbolic manifolds

Colin Guillarmou, Frederic Naud

摘要:

对于$n+1$维双曲空间的凸余紧群$Γ$的重正化迹,我们得到了一个将波算子的重正化迹与拉普拉斯算子的共振和边界的某些共形不变量联系起来的公式,推广了Guillopé和Zworski的一个公式.通过写这条迹的长度谱,我们证明了精确的渐近闭测地线的数量与一个有效的,指数小的误差项时,$Γ$的极限集的维数大于$n/2$。

英文摘要:

For quotients of the $n+1$-dimensional hyperbolic space by a convex co-compact group $Γ$, we obtain a formula relating the renormalized trace of the wave operator with the resonances of the Laplacian and some conformal invariants of the boundary, generalizing a formula of Guillopé and Zworski in dimension 2. By writing this trace with the length spectrum, we prove precise asymptotics of the number of closed geodesics with an effective, exponentially small error term when the dimension of the limit set of $Γ$ is greater than $n/2$.
