%0 Journal Article %T Virtually Haken fillings and semi-bundles %A Daryl Cooper %A Genevieve S Walsh %J Mathematics %D 2004 %I arXiv %R 10.2140/gt.2006.10.2237 %X Suppose that M is a fibered three-manifold whose fiber is a surface of positive genus with one boundary component. Assume that M is not a semi-bundle. We show that infinitely many fillings of M along dM are virtually Haken. It follows that infinitely many Dehn-surgeries of any non-trivial knot in the three-sphere are virtually Haken. %U http://arxiv.org/abs/math/0407328v5
