Zeta functions of virtually nilpotent groups
@article{Sulca2012ZetaFO, title={Zeta functions of virtually nilpotent groups}, author={Diego Sulca}, journal={Israel Journal of Mathematics}, year={2012}, volume={213}, pages={371-398} }
We prove that the subgroup zeta function and the normal zeta function of a finitely generated virtually nilpotent group are finite sums of Euler products of cone integrals over Q and we deduce from this that they have rational abscissa of convergence and some meromorphic continuation. We also define Mal’cev completions of a finitely generated virtually nilpotent group and we prove that the subgroup growth and the normal subgroup growth of the latter are invariants of its Q-Mal’cev completion.

We show that if two finitely generated nilpotent groups have isomorphic C-Mal’cev completions, then their subgroup (resp. normal) zeta functions have the same abscissa of convergence. A similar…

We prove that in every finitely generated profinite group, every subgroup of finite index is open; this implies that the topology on such groups is determined by the algebraic structure. This is…
