Ubiquitous quasi-Fuchsian surfaces in cusped hyperbolic $3$–manifolds
We prove that every finite-volume hyperbolic –manifold contains a ubiquitous collection of closed, immersed, quasi-Fuchsian surfaces. These surfaces are ubiquitous in the sense that their preimages in the universal cover separate any pair of disjoint, nonasymptotic geodesic planes. The proof relies in a crucial way on the corresponding theorem of Kahn and Markovic for closed –manifolds. As a corollary of this result and a companion statement about surfaces with cusps, we recover Wise’s theorem that the fundamental group of acts freely and cocompactly on a cube complex.
