A sign assignment in totally twisted Khovanov homology | Andrew Manion
; | Date: |
23 Sep 2011 | Abstract: | We lift the characteristic-2 totally twisted Khovanov homology of Roberts and
Jaeger to a theory with integer coefficients. The result is a complex computing
reduced odd Khovanov homology for knots. This complex is equivalent to a
spanning-tree complex whose differential is explicit modulo a sign ambiguity
coming from the need to choose a sign assignment in the definition of odd
Khovanov homology. | Source: | arXiv, 1109.4982 | Services: | Forum | Review | PDF | Favorites |
