Torsion in Khovanov link homology via chromatic graph cohomology
by
Dan Scofield
NCSU

The categorification of the chromatic polynomial by Helme-Guizon and Rong is isomorphic to Khovanov link homology over a range of homological gradings. Motivated by Hochschild homology, we compute torsion in chromatic homology for certain classes of graphs. As a consequence, we offer insight into Z2 torsion of certain classes of knots and links.
