Dehn Surgery

The operation of drilling a tubular Neighborhood of a Knot $K$ in $\Bbb{S}^3$ and then gluing in a solid Torus so that its meridian curve goes to a $(p,q)$-curve on the Torus boundary of the Knot exterior. Every compact connected 3-Manifold comes from Dehn surgery on a Link in $\Bbb{S}^3$.
