Oct 19, 2016 at 3:32 comment added Ian Agol I forgot that also Marty Scharlemann had a reworking of the proof of Property R (or rather the Poenaru conjecture) that was somewhat simpler (doing away with taut foliations, but using sutured manifold hierarchies). ams.org/mathscinet-getitem?mr=992331 I still wouldn't call the proof "simple" (neither is Gordon-Luecke's proof).

Jun 9, 2015 at 12:15 comment added Ian Agol @MikeMiller: yes, since 0-framed surgery is irreducible, the Seiberg-Witten Floer homology is non-trivial.
Jun 9, 2015 at 12:02 comment added mme @IanAgol: Thanks for the correction. I guess the interdependence comes from the use of the foliations constructed in "Foliations and the topology of 3-manifolds"?

Jun 9, 2015 at 8:45 comment added Ian Agol @MikeMiller: true, but these results actually depend on Property R.
Jun 9, 2015 at 4:54 comment added mme You can prove this (indeed, a more general theorem that $r$-surgery on a knot $K \subset S^3$ is diffeomorphic to $r$-surgery on the unknot iff $K$ is the unknot, $r \in \mathbb Q$) using monopole Floer homology or Heegaard Floer homology; see "Monopoles and Lens spaces surgeries" or "Holomorphic disks and genus bounds" respectively. As far as I know, though, this is in a much different direction than Agol and Wise's work.
