WebThere are a number of introductions to Khovanov homology. A good place to start is Dror Bar-Natan’s exposition of Khovanov’s work On Khovanov’s categorification of the Jones polynomial (Bar-Natan, [ 0201043 ] ) † † margin: 0201043 , WebFeb 27, 2016 · Kronheimer and Mrowka showed that the Khovanov homology detects the unknot. Bar-Natan showed a program to compute the Khovanov homology fast: there was no rigorous complexity analysis of the algorithm, but it is estimated by Bar-Natan that the algorithm runs in time proportional to the square root of the number of crossings, so it is … WebWe will define a Bar-Natan homology for null homologous links in RP^3. As in the case for the usual Bar-Natan homology, this gives rise to a s-invariant and certain genus bound for … take gabapentin with food
