%0 Journal Article %T Surfaces, submanifolds, and aligned Fox reimbedding in non-Haken 3-manifolds %A Martin Scharlemann %A Abigail Thompson %J Mathematics %D 2003 %I arXiv %X Understanding non-Haken 3-manifolds is central to many current endeavors in 3-manifold topology. We describe some results for closed orientable surfaces in non-Haken manifolds, and extend Fox's theorem for submanifolds of the 3-sphere to submanifolds of general non-Haken manifolds. In the case where the submanifold has connected boundary, we show also that the boundary-connected sum decomposition of the submanifold can be aligned with such a structure on the submanifold's complement. %U http://arxiv.org/abs/math/0308011v1
