#### Abstract

Igor Frenkel introduced the idea 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 Frenkel's proposal 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).
