### More Mathematical Blogging

#### Posted by David Corfield

More mathematics blogging at the Secret Blogging Seminar. This time a group blog manned by five recent and future Berkeley mathematics Ph.D.’s, at least 4 of whom have contributed comments to the Café, and who promise

Commentary on our own research, other mathematics pursuits and what ever seems like writing about on any given day. Sort of like a seminar, but with more rude commentary from the audience.

I see one of their number, A J Tolland, gave a talk Categorified TQFT & Quantum Groups (notes):

There’s some emerging folk wisdom which says that there’s a connection between the “n” in n-category and the “n” in n-dimensional. In this talk, we’ll explore one of the simplest examples of this phenomenon, showing how one can recover the axioms of a (finite) quantum group from path integral rules of a “categorically enriched” version of the topological QFT known as Chern-Simons theory. The finiteness restriction is necessary in this case to make the path integral into a well-defined mathematical object.

Sounds like there may be one or two common interests between blogs.

That’s great! We are getting slowly to the point which I was hoping for already yeras ago: all discussion needs – and much more – can be satisfied online.

But is it just me being blind, or don’t they provide any feeds for their blog (atom, rss, etc.)?

Now, that’s interesting! Unfortunately at the moment the slides break off right at the point where it becomes

reallyinteresting… :-)
