Rovelli has given his team and himself just seven months to advance LQG to a new stage. Why do I call this "throwing the eagle"? Because a Roman general would on occasion hurl his legion's eagle standard into the opposing army's midst, confident his side could rout their foes the recover it. http://penelope.uchicago.edu/Thayer/E/Roman/Texts/Florus/Epitome/1B*.html#11.2 In this case what has been undertaken is enterprising in its own way. The target date is mid-September, in time for a weeklong series of lectures at Corfu (13th thru 20th). http://www.maths.nottingham.ac.uk/qg/CorfuSS.html I've been to Corfu, a large island off the west coast of Greece, up near the border with Albania. It's beautiful. There will be a QG school, with a number of invited speakers giving seminars, plus 5 main speakers each giving a 'minicourse' series of lectures. The main speakers will be Ashtekar, Baez, Barrett, Rivasseau, and Rovelli. The website gives the titles and brief synopses of each minicourse. I'll quote Rovelli's: Covariant loop quantum gravity and its low-energy limit "I present a new look on Loop Quantum Gravity, aimed at giving a better grasp on its dynamics and its low-energy limit. Following the highly succesful model of QCD, general relativity is quantized by discretizing it on a finite lattice, quantizing, and then studying the continuous limit of expectation values. The quantization can be completed, and two remarkable theorems follow. The first gives the equivalence with the kinematics of canonical Loop Quantum Gravity. This amounts to an independent re-derivation of all well known Loop Quantum gravity kinematical results. The second [gives] the equivalence of the theory with the Feynman expansion of an auxiliary field theory. Observable quantities in the discretized theory can be identified with general relativity n-point functions in appropriate regimes. The continuous limit turns out to be subtly different from that of QCD, for reasons that can be traced to the general covariance of the theory. I discuss this limit, the scaling properties of the theory, and I pose the problem of a renormalization group analysis of its large distance behavior." Rovelli's course description is marked "tentative", presumably because work is still in progress to prove the theorems in every case. It will be extremely interesting to see if they can bring this project to full completion in the next few months.
