SUMMARY:Aaron Lauda\, \"Categorification of Quantum Groups\"
DESCRIPTION:Abstract: Crane and Frenkel proposed that 4-dimensional TQFT
 s could be obtained by categorifying quantum groups at root of unity usi
 ng their canonical bases. In my talk I will explain how the quantum enve
 loping algebra of quantum sl(2) at generic q can be categorified using a
  diagrammatic calculus. If time permits I will also explain joint work w
 ith Mikhail Khovanov on how this construction can be generalized to quan
 tum sl(n). No background on quantum groups will be assumed.
