%0 Journal Article %T Fast Khovanov Homology Computations %A Dror Bar-Natan %J Mathematics %D 2006 %I arXiv %X We introduce a local algorithm for Khovanov Homology computations - that is, we explain how it is possible to "cancel" terms in the Khovanov complex associated with a ("local") tangle, hence canceling the many associated "global" terms in one swoosh early on. This leads to a dramatic improvement in computational efficiency. Thus our program can rapidly compute certain Khovanov homology groups that otherwise would have taken centuries to evaluate. %U http://arxiv.org/abs/math/0606318v1
