Query: On mapping cones of Seifert fibered surgeries   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.
