算术富克斯群的等价迹集

Equivalent trace sets for arithmetic Fuchsian groups

Grant S. Lakeland

摘要:

我们证明了模群有一个无限族的有限指数子群,每个子群都有与模群本身相同的迹集。各种同余子群的模群,和Bianchi群,也被证明有这个属性。在模群的情况下,我们构造这样的有限指数子群的例子。

英文摘要:

We show that the modular group has an infinite family of finite index subgroups, each of which has the same trace set as the modular group itself. Various congruence subgroups of the modular group, and the Bianchi groups, are also shown to have this property. In the case of the modular group, we construct examples of such finite index subgroups.
