%0 Journal Article %T Once-punctured tori and knots in lens spaces %A Kenneth L. Baker %J Mathematics %D 2006 %I arXiv %X We determine the non-null homologous knots in lens spaces whose exteriors contain properly embedded once-punctured tori. All such knots arise as surgeries on the Whitehead link and are grid number 1 in their lens spaces. As a corollary, we classify once-punctured torus bundles that admit a lens space filling. %U http://arxiv.org/abs/math/0612525v2
