Calculating Bar-Natan's characteristic two Khovanov homology | Paul Turner
; | Date: |
10 Nov 2004 | Subject: | Geometric Topology; Quantum Algebra MSC-class: 57M25 | math.GT math.QA | Abstract: | We investigate Bar-Natan’s characteristic two Khovanov link homology theory studying both the filtered and bi-graded theories. The filtered theory is computed explicitly and the bi-graded theory analysed by setting up a family of spectral sequences. The E_2-pages can be described in terms of groups arising from the action of a certain endomorphism on mod 2 Khovanov homology. Some simple consequences are discussed. | Source: | arXiv, math.GT/0411225 | Services: | Forum | Review | PDF | Favorites |
