Closed quasi-Fuchsian subsurfaces of closed hyperbolic
3-manifolds constructed by J. Kahn and V. Markovic have played a crucial
role in the recent proof of the Virtual Haken Conjecture. In this talk, we
will investigate the techniques and construct homologically interesting
possibly bounded quasi-Fuchsian subsurfaces in closed hyperbolic
3-manifolds. We will focus on extending the geometric and topological
aspects from work of Kahn-Markovic, and will discuss further questions.
This is joint work with Vladimir Markovic.
