We construct two-dimensional families of complex hyperbolic structures on disc orbibundles
over the sphere with three cone points. This contrasts with the previously known examples of …

In $\mathrm {PU}(2, 1) $, the group of holomorphic isometries of the complex hyperbolic
plane, we study the space of involutions $ R_1, R_2, R_3, R_4, R_5 $ satisfying …

The non-trivial complete totally geodesic submanifolds of the complex hyperbolic plane
$\mathbb H_ {\mathbb C}^ 2$ are the complex geodesics and the real planes. We present …

We study surface groups Γ in SO (4, 1), which is the group of conformal automorphisms of S
3, and also the group of isometries of H 4. We consider such Γ so that its limit set Λ Γ is a …

We give a new self-contained proof of Poincaré's Polyhedron Theorem on presentations of
discontinuous groups of isometries of a Riemann manifold of constant curvature. The proof …
