Crane and Frenkel conjectured that the quantum enveloping
algebra of sl(2) could be categorified at generic q using its
canonical basis. In my talk I will describe a realization of this
conjecture using a diagrammatic calculus.
If time permits I will also explain joint work with Mikhail Khovanov
on how this construction can be generalized to quantum sl(n).
