Discreteness criteria based on a test map in PU (n,1). (English) Zbl 1270.30012
Summary: The discreteness of isometry groups in complex hyperbolic space is a fundamental problem. In this paper, discreteness criteria of a n-dimensional subgroup G of SU (n,1) are investigated by using a test map which may not be in G.
