Title of the talk: Trace of the categorified quantum sl(2), University of Texas at Austin, USA, November 3, 2014

Abstract: In this talk I will give a gentle introduction to the categorified quantum sl(2) and show that the trace (or 0th Hochschild homology) of this 2-category is isomorphic to the current algebra Usl(2)[t]. Then I'll discuss applications to the annular Khovanov homology.
