Spring schedule for International LQG Seminar

[marcus]

The ILQGS "conference call" seminars audio and slide go online, so we can listen. They usually have some 5 or so centers hooked up, so during the presentation you may hear comment/question from Marseille, Nottingham, PennState, Warsaw, Waterloo,...
Then sometimes the speaker will respond to the comment and sometimes someone else from another part of the world. It can get pretty interesting.

They now have a ILQGS blog. Only one post (by John Baez) there so far, and a couple of comments. If it gets going it could be an interesting blog. More people could ask questions about the seminar presentations---those who listen but can't ask questions in real time.

The list of past seminar talks, and links to the audio and slides PDF, are here:

Matteo Smerlak gave a good talk recently. Jerzy Lewandowski gave two.

I'll copy the list of speakers scheduled for Spring 2011.Jan 18 Inflationary observables and observational constraints in LQC Gianluca Calcagni (AEI)

Feb 01 Spinfoam cosmology Francesca Vidotto (Marseille)

Feb 15 Semiclassicality of the loop quantum universe Tomasz Pawlowski (UNB)

Mar 01 The principle of relative locality Laurent Freidel (PI)

Mar 15 Quantum deformation of 4d spin foam models Winston Fairbairn (Hamburg)

Mar 29 Observational signatures in LQC Abhay Ashtekar (PennState)

Apr 12 Simplicity constraints and the role of the Immirzi parameter in quantum gravity James Ryan (AEI)

Apr 26 1/N Expansion for spin foams Razvan Gurau (PI)

May 10 Group field theory: a hint of renormalization Aristide Baratin (Paris-Orsay)When I google "principle [of] relative locality" the only exact hit I get is the announcement of Freidel's talk on ILQGS. So is the principle of relative locality a new principle? Freidel's talk seems to overlap with the Zakopane school (except for the time difference). I'm curious what Freidel means by relative locality.

There's been mention several times here at PF Beyond forum of the possibility of LQG renormalization via Group Field Theory. There is already a bunch of papers and talks about formulating spinfoam LQG in GFT. Razvan Gurau and Aristide Baratin have both contributed papers on that.

Let' see if we can guess what relative locality is. Or at least the context in which he will be working.
