Bianchi Groups Are Conjugacy Separable

We prove that non-uniform arithmetic lattices of SL2(C) and in particular the Bianchi groups are conjugacy separable. The proof based on recent deep results of Agol, Long, Reid and Minasyan.

Hyperbolic Tessellations Associated to Bianchi Groups

Let F/Q be a number field. The space of positive definite binary Hermitian forms over F form an open cone in a real vector space. There is a natural decomposition of this cone into subcones. In the case of an imaginary quadratic field these subcones descend to hyperbolic space to give rise to tessellations of 3-dimensional hyperbolic space by ideal polytopes. We compute the structure of these p...

One-Cusped Congruence Subgroups of Bianchi Groups

We show that there are only finitely many maximal congruence subgroups of the Bianchi groups such that the quotient by H has only one cusp.
