If you have a question about this talk, please contact Dr Andras Juhasz .

Introducing a long twist into a pair of strands in a knot diagram gives rise to a simple tensor factor of its (Khovanov or Khovanov-Rozansky) knot homology. We explore how some straightforward homological algebra can be brought to bear in this situation and deduce some consequences.
