Divisibility of great webs and reducible Dehn surgery
Nicholas Zufelt
We use the combinatorial techniques of graphs of intersection to study reducible Dehn surgeries on knots in the three-sphere. In particular, in the event that a reducible surgery o…

Reducible surgeries and Heegaard Floer homology
Jennifer Hom, Tye Lidman, Nicholas Zufelt
In this paper, we use Heegaard Floer homology to study reducible surgeries. In particular, suppose K is a non-cable knot in the three-sphere with an L-space surgery. If p-surgery o…
