Nielsen Methods and Groups Acting on Hyperbolic Spaces

  • Published 2002

Abstract

We show that for any n ∈ N there exists a constant C(n) such that any n-generated group G which acts by isometries on a δ-hyperbolic space (with δ > 0) is either free or has a nontrivial element with translation length at most δC(n).
