While everybody is paying attention to Strings 05, I would like to mentionRaw Message

that at the same time there is a big conference on mathematical physics

going on in Sydney, with lots of stuff related to String Theory:

http://streetfest.maths.mq.edu.au/ .

A couple of participants of this conference are currently liveblogging from

Sydney at the String Coffee Table,

http://golem.ph.utexas.edu/string/archives/000591.html ,

providing lots of information.

For instance:

- Bondal has been talking about mirror symmetry on toric varieties:

http://golem.ph.utexas.edu/string/archives/000596.html

- Bouwknegt has been talking about applying Hitchin's generalized geometry

to A- and B-branes and mirror symmetry:

http://golem.ph.utexas.edu/string/archives/000601.html

- Mueger has been talking about CFT in the language of modular categories

and how this is useful for describing strings on orbifolds:

- In a similar contex J. Fuchs and I. Runkel will talk about CFTs and

Frobenius algebras:

- Gorbunov will relate Witten's "half-twisted sigma-model" to gerbes

-Porter will talk about "Homotopy Quantum Field Theories":

which, I am being told, have something to say about strings on orbifolds:

- Then there are at least three lectures on "higher gauge theory" related to

"nonabelian strings", by Baez, Getzler and Kapranov.

- After preparation by J. Baez and A. Crans,

D. Stevenson will talk about our result how the String-group, which

describes the parallel transport of superstrings,

http://golem.ph.utexas.edu/string/archives/000571.html

is neatly expressed in terms of Lie 2-algebra and Lie 2-group theory:
