A complex hyperbolic triangle group is a group generated by three involutions fixing complex lines in complex hyperbolic space. Our purpose in this paper is to improve a previous result and to discuss discreteness of complex hyperbolic triangle group

Jorgensen's inequality gives a necessary condition for a nonelementary two generator group of isometries of hyperbolic space to be discrete. We give analogues of Jorgensen's inequality for nonelementary groups of isometries of complex hyperbolic 2-sp

In the study of a geometrically finite kleinian group, the properties of points of approximation are discussed (see [2]). We show that ifG is a discrete subgroup ofU(1, n; C) acting on the complex unit ballBn, then a point of approximation ofG has si

Let U(1, n; ℂ) be the automorphism group of the Hermitian formfor . We can regard an element of U(1, n; ℂ) as a transformation acting on , where is the closure of the complex unit ballThe non-trivial elements of U(1, n; ℂ) fall into three conju

We give a version of Shimizu's lemma for groups of complex hyperbolic isometries one of whose generators is a parabolic screw motion. Suppose that G is a discrete group containing a parabolic screw motion A and let B be any element of G not fixing th

Let $G$ be a discrete subgroup of $PU(1,n; \mathbf{C})$. For a boundary point $y$ of the Siegel domain, we define the generalized isometric sphere $I_y(f)$ of an element $f$ of $PU(1,n; \mathbf{C})$. By using the generalized isometric spheres of elem
