### Ultra-parallel complex hyperbolic triangle groups

Geometry and Topology Seminar

20th February 2024, 2:00 pm – 3:00 pm

Fry Building, 2.04

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.
