Colored tangle invariants and sl(2) categorification

Vortrag von Prof. Dr. Joshua Sussan
Datum: 15.11.10   Zeit: 15.00 - 16.00   Raum: Y27H25

We review the categorification of tensor products of finite-dimensional quantum sl(2) representations using categories of Harish-Chandra bimodules. We then extend this construction to an invariant of tangles whose strands are colored by the natural numbers. This is a categorical version of the Reshetikhin-Turaev invariant for quantum sl(2).
