Nielsen equivalence in Fuchsian groups

Abstract

We give a complete classification of minimal generating systems in a very general class of Fuchsian groups $G “$ . This class includes for example any $G$ which has at least seven nonconjugate cyclic subgroups of order $γ_{i} \geq 3$ . In particular, the well-known problematic cases where $G$ has characteristic exponents $γ_{i} = 2$ are not excluded.

We classify generating systems up to Nielsen equivalence; this notion is strongly related to Heegaard splittings of $3$ –manifolds. The results presented here provide in particular the tools for a rather general extension of previous work of the authors and others on the isotopy classification of such splittings in Seifert fibered spaces.
