Torsion calculations in Khovanov cohomology.

Schuetz, Dirk (2020) 'Torsion calculations in Khovanov cohomology.', Journal of knot theory and its ramifications., 29 (8). p. 2071001.


We obtain information on torsion in Khovanov cohomology by performing calculations directly over Z/pkZ for p prime and k≥2. In particular, we get that the torus knots T(9,10) and T(9,11) contain torsion of order 9 and 27 in their Khovanov cohomology.
