算术双曲3-轨道的Salem数的计数

Counting Salem numbers of arithmetic hyperbolic 3-orbifolds

Mikhail Belolipetsky, Matilde Lalín, Plinio G. P. Murillo, Lola Thompson

摘要:

已知算术双曲轨道的闭测地线的长度与Salem数有关。我们对这一现象进行了定量研究。我们证明了任何非紧算术$3$维orbifold定义$c Q^{1/2} + O(Q^{1/4})$平方根Salem数的程度$4$小于或等于$Q$。这个数量可以与这样的塞勒姆数的总数进行比较,这被证明是渐近的$\frac{4}{3}Q^{3/2}+O(Q)$。假设Marklof的间隙猜想,我们可以将这些结果推广到紧算术$3$ -orbifolds。作为应用,我们得到了非紧偶维算术轨道的测地谱中平均重数的强指数增长性的下界。以前,这样的下界仅在维度$2$和$3$中获得。

英文摘要:

It is known that the lengths of closed geodesics of an arithmetic hyperbolic orbifold are related to Salem numbers. We initiate a quantitative study of this phenomenon. We show that any non-compact arithmetic $3$-dimensional orbifold defines $c Q^{1/2} + O(Q^{1/4})$ square-rootable Salem numbers of degree $4$ which are less than or equal to $Q$. This quantity can be compared to the total number of such Salem numbers, which is shown to be asymptotic to $\frac{4}{3}Q^{3/2}+O(Q)$. Assuming the gap conjecture of Marklof, we can extend these results to compact arithmetic $3$-orbifolds. As an application, we obtain lower bounds for the strong exponential growth of mean multiplicities in the geodesic spectrum of non-compact even dimensional arithmetic orbifolds. Previously, such lower bounds had only been obtained in dimensions $2$ and $3$.
