Geometric finiteness in negatively pinched Hadamard manifolds. (English) Zbl 1512.53035

Summary: In this paper, we generalize Bonahon’s characterization of geometrically infinite torsion-free discrete subgroups of \(\mathrm{PSL}(2,\mathbf C)\) to geometrically infinite discrete subgroups \(\Gamma\) of isometries of negatively pinched Hadamard manifolds \(X\). We then generalize a theorem of Bishop to prove that every discrete geometrically infinite isometry subgroup \(\Gamma\) has a set of nonconical limit points with the cardinality of the continuum.
