Within Rovellian aesthetics (which I'm not fond of), it'd be used to calculate the semiclassical limit - the limit that Bianchi, Perini, Magliaro, Ding etc are now trying to look at by taking the Immirzi parameter to zero. Rovelli's latest review indicates he understands this is kludgey, and a more proper method is needed.I know that Dittrich et al is largely about Migdal-Kadanoff method and they say a lot about the ability to calculate. What I am curious about is calculating WHAT? Can you or anyone help me imagine what kind of massive lattice calculation might be in view? Can you see how this might connect up with CMB observations, for instance, or with some other data?
The other thing philosophy which Dittrich seems open to - a more Smolinesque or at least Perimeterish inclination - is that maybe there's a link between the http://arxiv.org/abs/1010.5437" [Broken] proposals.
Thanks, I'll check it out!BTW Atyy, Eugenio Bianchi in his 21 September PIRSA talk referred to something of XG Wen.
It is on one of those slides. I checked: slide 23/24 on page 46/48 of the PDF
