The homotopy theory of Khovanov homology
arXiv:1112.3460 · doi:10.2140/agt.2014.14.2747
Abstract
We show that the unnormalised Khovanov homology of an oriented link can be identified with the derived functors of the inverse limit. This leads to a homotopy theoretic interpretation of Khovanov homology.
