Complex Hyperbolic Triangle Groups of Type
arXiv:1901.01572 · doi:10.1090/ecgd/348
Abstract
In this paper we study discreteness of complex hyperbolic triangle groups of type , i.e. groups of isometries of the complex hyperbolic plane generated by three complex reflections of orders in complex geodesics with pairwise distances . For fixed the parameter space of such groups is of real dimension one. We determine intervals in this parameter space that correspond to discrete and to non-discrete triangle groups.
