On mapping cones of Seifert fibered surgeries
arXiv:1110.5934 · doi:10.1112/jtopol/jts008
Abstract
Using the mapping cone of a rational surgery, we give several obstructions for Seifert fibered surgeries, including obstructions on the Alexander polynomial, the knot Floer homology, the surgery coefficient and the Seifert and four-ball genus of the knot.
