Odd torsion in the Khovanov homology of semi-adequate links

Coauthors: Radmila Sazdanovic

Shumakovitch showed that the Khovanov homology of an alternating link does not contain odd torsion. We adapt his proof to show that chromatic graph cohomology does not contain odd torsion. Then we use a partial isomorphism between chromatic graph cohomology and Khovanov homology to show that semi-adequate links do not contain odd torsion in certain gradings.
