Kleinian groups via strict hyperbolization
Beibei Liu
In this paper, we construct Kleinian groups from the direct product of copies of the rank 2 free group via strict hyperbolization. We g…

Hausdorff dimension of non-conical limit sets
Michael Kapovich, Beibei Liu
Geometrically infinite Kleinain groups have nonconical limit sets with the cardinality of the continuum. In this paper, we construct a geometrically infinite Fuchsian group such th…

Geometric infiniteness in negatively pinched Hadamard manifolds
Michael Kapovich, Beibei Liu
We generalize Bonahon's characterization of geometrically infinite torsion-free discrete subgroups of PSL(2, ) to geometrically infinite discrete isometry subgroups in…
