I am interested in peoples opinion on the following papers,(adsbygoogle = window.adsbygoogle || []).push({});

hep-th/0307026 Inflation and de Sitter holography

hep-th/0402050 Holography, diffeomorphisms, and scaling violations in the CMB

Larson and McNees motivated from Maldecena's ADS/CFT

analyze Inflation using the Spectulated dS/CFT

using Renormalization group equations derived from requiring the H-J

functional does not diverge in the IR limt (they use counter terms to control this) and that the renormalised action is invariant under diffeomorphism RG improved spectral index for scalar and tensors perturbations are calculated. They reproduce standard slow roll results

for the spectral index n_s

Also If anyone was familar with the explicit derivation for the equation for the

power spectrum given in hep-th/0402050 Eq (133) and the results Eq(136)

I would be very interested to know how these were derived the paper is not very clear in my opinion and I have to to be able to reproduce there resuts

thanks
