$[m_1,m_2,0]$型超平行复双曲三角群的离散性

Discreteness of Ultra-Parallel Complex Hyperbolic Triangle Groups of Type $[m_1,m_2,0]$

Andrew Monaghan, John R. Parker, Anna Pratoussevitch

摘要:

本文考虑$[m_1,m_2,0]$型超平行复双曲三角形群,即复双曲平面的等距群,它们是由三条超平行复测地线中的两条在边界上相交的复测地线的复反射所生成的。我们证明了这些群的离散性和非离散性结果,并讨论了离散性结果与某些群元素的椭圆性之间的联系。

英文摘要:

In this paper we consider ultra-parallel complex hyperbolic triangle groups of type $[m_1,m_2,0]$, i.e. groups of isometries of the complex hyperbolic plane, generated by complex reflections in three ultra-parallel complex geodesics two of which intersect on the boundary. We prove some discreteness and non-discreteness results for these groups and discuss the connection between the discreteness results and ellipticity of certain group elements.
