C04005 - Workshop on Quantum Gravity in the Americas: Status and future directions The goal of the workshop is to bring together Quantum Gravity researchers working in the Americas to share their approaches and results, draw connections between research efforts, develop a broader perspective on the issues, focus on outstanding problems, foster an interactive community, and set objectives for future research. This workshop is a following-up of the workshop organized in January in Mexico. http://pirsa.org/podcast/C04005 Science 2009 http://blogs.law.harvard.edu/tech/rss en-ca Thu, 08 Jan 2009 12:04:45 -0500 sbradwell@perimeterinstitute.ca Thu, 08 Jan 2009 12:04:45 -0500 G 180 pirsa-admin@perimeterinstitute.ca Steve Bradwell's - Podcast Generator About Semi-Classical Quantum Gravity Alejandro Corichi http://streamer.perimeterinstitute.ca/mp3/8ceae4d5-1e02-4ec0-8c3f-0b575c6c9c22.mp3 Science http://streamer.perimeterinstitute.ca/mp3/8ceae4d5-1e02-4ec0-8c3f-0b575c6c9c22.mp3 Fri, 29 Oct 2004 02:00:00 -0400 Physical Ramifications of Quantum Geometry Malcom http://streamer.perimeterinstitute.ca/mp3/452478bc-070b-4fbd-a56a-97c147e04752.mp3 Science http://streamer.perimeterinstitute.ca/mp3/452478bc-070b-4fbd-a56a-97c147e04752.mp3 Fri, 29 Oct 2004 09:00:00 -0400 The Problem of Dynamics in Quantum Gravity John Baez http://streamer.perimeterinstitute.ca/mp3/bd2dc921-5981-4216-baed-26e5cc76c8bd.mp3 Science http://streamer.perimeterinstitute.ca/mp3/bd2dc921-5981-4216-baed-26e5cc76c8bd.mp3 Fri, 29 Oct 2004 10:00:00 -0400 Is a past finite order the inner basis of space-time?

-0500 3d quantum gravity and deformed special relativity In 3d quantum gravity, Planck's constant, the Planck length and the cosmological constant control the lack of (co)-commutativity of quantities like angular momenta, momenta and postion coordinates. I will explain this statement, using the quantum groups which arise in the 3d quantum gravity but avoiding technical details. The non-commutative structures in 3d quantum gravity are quite different from those in the deformed version of special relativity desribed by the kappa-Poincare group, but can be related to the latter by an operation called semi-dualisation. I will explain this operation, and make comments on its possible physical significance. The talk is based on joint work with Shahn Majid.
