Knot floer homology detect unlink
Webits knot Floer homology, implying that Floer homology solves the word problem for mapping class groups of surfaces with non-empty boundary. Finally, we survey some conjectures and questions and, based on the results described above, formulate some new ones.

WebHeegaard Floer homology, de ned by Ozsv ath-Szabo [OS04d], and knot Floer homology, de ned by Ozsv ath-Szab o [OS04b] and independently Rasmussen [Ras03], are invariants of 3-manifolds and knots inside of them. These notes aim to provide an overview of these invariants and the relationship between them. WebAdditionally we identify infinitely many pairs of links such that both links in the pair are each detected by link Floer homology but have the same Khovanov homology and knot Floer homology. Finally, we use some of our knot Floer detection results to give topological applications of annular Khovanov homology.

WebKhovanov homology of K2 to the Ozsv´ath-Szabo Floer homology of the branched dou-ble cover of K2. The Thurston norm of this latter manifold is non-trivial in the case when K is non-trivial. Since Ozsv´ath-Szab´o Floer homology detects the Thurston norm, this forces the rank of Floer homology, and hence the rank of Khovanov ho-mology, to grow.
