Ultra-parallel complex hyperbolic triangle groups

Ultra-parallel complex hyperbolic triangle groups are groups of complex hyperbolic isometries generated by three complex reflections with pair-wise disjoint fixed point sets. In this talk, I will discuss some discreteness and non-discreteness criteria for this class of groups. This is joint work with A. Monaghan and J.R. Parker and with S. Povall.
