Subgroup growth of lattices in semisimple Lie groups

A. Lubotzky, N. Nikolov

We give very precise bounds for the congruence subgroup growth of arithmetic groups. This allows us to determine the subgroup growth of irreducible lattices of semisimple Lie group…

Counting primes, groups and manifolds

D. Goldfeld, A. Lubotzky, N. Nikolov +1

Let $Λ = SL_{2} (Z)$ be the modular group and let $c_{n} (Λ)$ be the number of congruence subgroups of $Λ$ of index at most $n$ . We prove that $\lim\limits_{n\to \infty} \fr…
