Khovanov homology with mod 2 coefficients
The following Python files were used to produce data for the paper
Two-fold quasi-alternating links, Khovanov homology and instanton homology written with Matt Stoffregen.
-
kh_mod2.py, reduced Khovanov homology with mod 2 coefficients
-
kh_twisted.py, Twisted Khovanov homology for a two-fold marked link
-
kh_dotted.py, Dotted diagram homology of a two-fold marked diagram
The first file is a basic script that computes the reduced Khovanov homology of a link with mod 2 coefficients. The second and third files are modifications that compute the variants of Khovanov homology that we considered in our paper. In particular, the table at the end of our paper was produced using these files. For an explanation of how to use the code, see:
