Heegaard splittings and Morse-Smale flows
We describe three theorems which summarize what survives in three dimensions of Smale's proof of the higher-dimensional Poincaré conjecture. The proofs require Smale's cancellation lemma and a lemma asserting the existence of a 2-gon. Such 2-gons are the analogues in dimension two of Whitn...

description |
We describe three theorems which summarize what survives in
three dimensions of Smale's proof of the higher-dimensional
Poincaré conjecture. The proofs require Smale's cancellation
lemma and a lemma asserting the existence of a 2-gon. Such
2-gons are the analogues in dimension two of Whitney disks in
higher dimensions. They are also embedded lunes; an (immersed)
lune is an index-one connecting orbit in the Lagrangian Floer
homology determined by two embedded loops in a 2-manifold. |
