WebTHE BAR-NATAN HOMOLOGY AND UNKNOTTING NUMBER AKRAM ALISHAHI Abstract. We show that the order of torsion homology classes in Bar-Natan deformation of Khovanov … WebIn 2006 Dror Bar-Natan developed a computer program to calculate the Khovanov homology (or category) for any knot. Related theories. One of the most interesting aspects of Khovanov's homology is that its exact sequences are formally similar to those arising in the Floer homology of 3-manifolds.
