John Baez just posted this announcement and tentative schedule for a conference this month at the Albert Einstein Institute (Max Planck Institute for Gravitation Physics) on the outskirts of Berlin.

We have had several threads at PF studying work by AEI people---Hanno Sahlmann, Martin Bojowald,...

Here's John Baez announcement:

Announcement of AEI Symposium 29 - 31 October, 2003

"STRINGS MEET LOOPS"

Organizers: A. Ashtekar (PSU) and H. Nicolai (AEI)

The primary purpose of this meeting is to bring together researchers working on string theory on the one hand, and on canonical and loop quantum gravity on the other, and to enhance exchange of ideas between the two communities. The program will consist of talks that will not be too technical, and should be primarily addressed to the other community. Their main purpose is to serve as a concrete platform for subsequent discussions. Each one hour talk will be followed by half an hour of discussion. The discussion need not be restricted to the material presented by the speaker, but should cover the general area of the talk. We expect a lively and frank exchange of ideas and anticipate many probing questions from the audience and participants who may have a different perspective on the subject than speakers.

For further information concerning participation in this symposium,
