What would you consider the best online resources for learning the 3+1 ADM formalism and gauge invariant perturbation theory in cosmology? (Assuming intermediate level GR and QFT familiarity)

As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, visit the help center for guidance.If this question can be reworded to fit the rules in the help center, please edit the question.

@Qmechanic: Why did you close the question more than 2 years after it was asked!? – MBN May 3 '13 at 9:58
@MBN I closed it because we only allow a few well-posed book recommendation questions. This question really ask about two different subjects. Mitchell Porter: It is my understanding that closure not necessarily mean deletion. – Qmechanic May 3 '13 at 10:41
@MitchellPorter see this and related meta discussion about the policies concerning study material and references. – Dilaton May 6 '13 at 9:45

Hah, I just studied this a while ago with James Bardeen, so I would say he is the best resource for learning this! Since you probably don't have access to the physical Bardeen, you can check out:

Physical Review D, Vol 22 no 8 (1980) "Gauge-invariant cosmological perturbations"


Physical Review D, Vol 40 no 6 (1989) "Designing density fluctuation spectra in inflation"

There is also a set of lecture notes I have sitting on my desk by him that claim they are "to be published in Particle Physics and Cosmology" which are dated 1988, so presumably they were published within the next year or so.

If you can find them, the talks are probably the easier of the three, and the first PrD article is the second easiest. The third paper is very nice, but more technically difficult.

Is the third one "Cosmological Perturbations from Quantum Fluctuations to Large Scale structure"? Because that's the "starred" reference in a Part III DAMTP lecture I'm attending, but the article simply doesn't seem to be online anywhere. – dbrane Jan 21 '11 at 12:12
Yes, it is. It seems to be published in a book, maybe you can get it through your library or interlibrary loan? – Mr X Jan 22 '11 at 16:02

The single best reference for learning about gauge-invariant cosmological perturbation theory is ch. 7 of Mukhanov's book Physical foundations of Cosmology. Ok, not an online resource, but still the very best if that's what you're looking for.

On doing a search for one of York's original papers I ran into this wonderful site by Luca Bombelli at Ole' Miss (University of Mississippi). This contains a very comprehensive bibliography on the initial-value problem. I would also recommend Robert Wald's GR book. It has very nice coverage of the IVP in chapters and in an appendix.

+1 for referencing Mukhanov's book, which I've consistently to found to be useful and clear. – Matt Reece Jan 21 '11 at 5:43
