富克斯群的Nielsen等价性

Nielsen Equivalence in Fuchsian groups

Martin Lustig, Yoav Moriah

摘要:

本文给出了一类非常一般的富克斯群G的极小生成系的完全分类。这个类包括例如任何G,它至少有七个非共轭循环子群的阶数大于大于2。特别地,不排除G具有等于2的特征指数的公知的有问题的情况。我们分类生成系统的尼尔森等价,这一概念是密切相关的Heegaard分裂的3流形。本文的结果提供了特别的工具,而一般的扩展以前的工作的作者和其他人,在Seifert纤维空间的这种分裂的合痕分类。

英文摘要:

In this paper 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 non-conjugate cyclic subgroups of order greater than 2. In particular, the well known problematic cases where G has characteristic exponents equal to 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 of this paper 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.
