Normal Subgroup Growth of Linear Groups: the (G2; F4;E8)-Theorem

Michael Larsen, Alexander Lubotzky

Let G be a finitely generated group and M_n(G) the number of its normal subgroup subgroups of index at most n. For linear groups G we show that M_n(G) can grow polynomially in n on…

Sieve methods in group theory I: Powers in Linear groups

Alexander Lubotzky, Chen Meiri

A general sieve method for groups is formulated. It enables one to "measure" subsets of a finitely generated group. As an application we show that if is a finitely generated no…
