The crystal commutor and Drinfeld's unitarized R-matrix
Joel Kamnitzer, Peter Tingley
Drinfeld defined a unitarized R-matrix for any quantum group U_q(g). This gives a commutor for the category of U_q(g) representations, making it into a coboundary category. Henriqu…

Knot homology via derived categories of coherent sheaves I, sl(2) case
Sabin Cautis, Joel Kamnitzer
Using derived categories of equivariant coherent sheaves, we construct a categorification of the tangle calculus associated to sl(2) and its standard representation. Our constructi…
