Hyperbolic three-manifolds that embed geodesically
arXiv:1510.06325
Abstract
We prove that every complete finite-volume hyperbolic 3-manifold that is tessellated into (embedded) right-angled regular polyhedra (dodecahedra or ideal octahedra) embeds geodesically in a complete finite-volume connected orientable hyperbolic 4-manifold , which is also tessellated into right-angled regular polytopes (120-cells and ideal 24-cells). If is connected, then Vol() < Vol(). This applies for instance to the Borromean link complement. As a consequence, the Borromean link complement bounds geometrically a hyperbolic 4-manifold.
