CFT, Gerbes and K-Theory in Oberwolfach, VII
Posted by Urs Schreiber
You’ll have noticed that I failed to report on the talks of the last two days in Oberwolfach, either because I was too tired, or too occupied or both. Here are some symposium-postprocessing notes.
Update: Peter Woit has followed the Oberwolfach discussion here and has written a related entry.
While searching for literature on what I now know is called ‘differential’ or ‘smooth’ K-theory I came across the report of another recent Oberwolfach workshop which is very closely related to the things I mentioned here recently:
P. Teichner & St. Stolz (Eds.)
Geometric Topology and Connections with Quantum Field Theory
OW Report No. 27/2005
This report is valuable for the references it assembles.
In the above fashion, every participant of an Oberwolfach workshop is supposed to provide a summary of his talk for the OW-Reports. A draft for my summary is the one below:

With kind permission, here are more details on Brano Jurčo’s talk:
Branislav Jurčo
On the Classification of Nonabelian Bundle Gerbes with Connections
(in preparation)
Update 5th October 2005: The corresponding preprint has now appeared as math.DG/0510078.

Wednesday in Oberwolfach. The obstructions for the sun to shine finally lifted and we had something that even people from Australia would recognize as a summer day.
The workshop now has a webpage on which links to slides and other background information will eventually appear:
Workshop Gerbes, twisted K-theory and conformal field theory

This evening in Oberwolfach: Talks on open strings in WZW models and lots of private discussion.

Oberwolfach is the mixture of a Zen monastery with a mathematical bioreactor. Nice experience.

K-theory for dummies, I
Posted by Urs Schreiber
I feel like talking about K-theory, K-homology, and the like. Here I start leisurely with a bird’s eye overview of some central ideas.

Next week I’ll be attending a mini-workshop at the MFO in Oberwolfach titled
Gerbes, Twisted K-Theory and Conformal Field Theory,
organized by Branislav Jurčo, Jouko Mickelsson and Christoph Schweigert.
If possible, I’ll try to report on this and that here at the Coffee Table.
