Khovanov homology detects split links
نویسندگان
چکیده
Extending ideas of Hedden-Ni, we show that the module structure on Khovanov homology detects split links. We also prove an analogue for untwisted Heegaard Floer branched double cover. Technical results proved along way include two interpretations in terms twisted and fact reduced complex a link is well defined up to quasi-isomorphism.

Khovanov Homology Detects the Trefoils
We prove that Khovanov homology detects the trefoils. Our proof incorporates an array of ideas in Floer homology and contact geometry. It uses open books; the contact invariants we defined in the instanton Floer setting; a bypass exact triangle in sutured instanton homology, proven here; and Kronheimer and Mrowka’s spectral sequence relating Khovanov homology with singular instanton knot homolo...
متن کاملBar-natan’s Khovanov Homology for Coloured Links
Using Bar-Natan’s Khovanov homology we define a homology theory for links whose components are labelled by irreducible representations of Uq(sl2). We then compute this explicitly.
متن کاملOpen-closed TQFTs extend Khovanov homology from links to tangles
We use a special kind of 2-dimensional extended Topological Quantum Field Theories (TQFTs), so-called open-closed TQFTs, in order to extend Khovanov homology from links to arbitrary tangles, not necessarily even. For every plane diagram of an oriented tangle, we construct a chain complex whose homology is invariant under Reidemeister moves. The terms of this chain complex are modules of a suita...
متن کاملLegendrian links and the spanning tree model for Khovanov homology
The Khovanov homology has led to many interesting new developments in knot theory and related fields. See Lee [4, 5], Ng [6], Plamenevskaya [7] and Rasmussen [8] for examples. It is still very difficult to compute the Khovanov homology in general. Recently, A Champanerkar and I Kofman [2] and, independently, S Wehrli [11] constructed a spanning tree model for the Khovanov homology based on the ...
متن کاملKhovanov-rozansky Homology of Two-bridge Knots and Links
We compute the reduced version of Khovanov and Rozansky’s sl(N) homology for two-bridge knots and links. The answer is expressed in terms of the HOMFLY polynomial and signature.
