### 3D TFT Literature

#### Posted by Urs Schreiber

As you may have noticed, I am beginning to learn about the 3D TFT approach towards 2D CFT. Here is a collection of some useful background literature which happens to be available online (thus circumventing the more ambitious task of listing the standard literature available in print).

As mentioned already, this brand new thesis is a great introduction to many important concepts

Bruce Bartlett
**Categorical Aspects of Topological Quantum Field Theories**

math.QA/0512103

A fundamental textbook

B. Bakalov & A. Kirillov
** Lectures on tensor categories and modular functors**

AMS, University Lecture Series, (2000)

has been made available online by Alxander Kirillov: here.

At that site you’ll also find a link to a useful set of notes

Kevin Walker
**On Witten’s 3-Manifold Invariants**

- old version

- draft of new version

Eventually I hope to extend this list, but for now that’s it. Hints are welcome.
