Sep 27, 2016 at 7:55 | comment | added | Marco Golla | @magicker72: I think that you only get $S^3$ by doing (integral) surgeries along $\{*\}\times S^1$. In the 4-dimensional cobordism picture, you are attaching a 2-handle that cancels the 1-handle. However, if I'm not mistaken, the answer to the original question is yes; in fact, $L(p,1)$ is an integral surgery along any $T(2,2q)$, and this is a good exercise with handle diagrams. | |

By Lickorish’s theorem, any three-manifold $M$ can be obtained by surgery on a link $\mathbb{L}$ in $S^3$, thus in $S^2\times S^1$. While the Lens space $L(p,1)$ is homeomorphic to $S^3/\mathbb{Z}_p$. Thus I wish to set up a connection between $L(p,1)$ and $T(2,2p)$. @magicker72 | |

Sep 27, 2016 at 0:46 | comment | added | magicker72 | Why are you focusing on a link? $S^3$ is surgery on $\{*\}\times S^1 \subset S^2 \times S^1$, and every $L(p, 1)$ is surgery on the same knot. | |
