The subgroup growth spectrum of virtually free groups
For a finitely generated group denote by the growth
coefficient of , that is, the infimum over all real numbers such
that . We show that the growth coefficient of a virtually
free group is always rational, and that every rational number occurs as growth
coefficient of some virtually free group. Moreover, we describe an algorithm to
compute

Periodicity of free subgroup numbers modulo prime powers
We completely characterise when the sequence of free subgroup numbers of a
finitely generated virtually free group is ultimately periodic modulo a given
prime power.Comment: AmS-LaTeX; 18 page
