Abstract

We describe a criterion for a real or complex hyperbolic lattice to admit a residually finite rational solvable (RFRS) tower that consists entirely of congruence subgroups. We use this to show that certain Bianchi groups PSL 2 (𝒪 d ) are virtually fibered on congruence subgroups, and also exhibit the first examples of RFRS Kähler groups that are not a subgroup of a product of surface groups and abelian groups.

一致性RFRS塔

我们描述了一个实双曲格或复双曲格允许一个完全由同余子群组成的剩余有限有理可解(RFRS)塔的准则。我们利用这一点证明了某些Bianchi群PSL 2 ( d)实际上是由同余子群构成的，并首次证明了RFRS Kähler群不是曲面群与阿贝尔群乘积的子群。

期刊介绍： The Annales de l’Institut Fourier aim at publishing original papers of a high level in all fields of mathematics, either in English or in French. The Editorial Board encourages submission of articles containing an original and important result, or presenting a new proof of a central result in a domain of mathematics. Also, the Annales de l’Institut Fourier being a general purpose journal, highly specialized articles can only be accepted if their exposition makes them accessible to a larger audience.
