Ampleness in the free group
We show that the theory of the free group -- and more generally the theory of any torsion-free hyperbolic group -- is $n$-ample for any $n\geq 1$. We give also an... -

We give an asymptotic estimate for the growth of prime conjugacy classes in a finitely generated free group. -
