Discussion Overview
The discussion centers around finding references for the decomposition of perturbations into scalar, vector, and tensor components, particularly in the context of cosmological perturbation theory. Participants seek detailed resources and reviews that cover this topic comprehensively.
Discussion Character
- Exploratory, Technical explanation, Meta-discussion
Main Points Raised
- One participant requests a good reference for the decomposition of perturbations into scalar, vector, and tensor parts.
- Another participant suggests a review on CMB anisotropies but notes it may not contain the desired decomposition details.
- A later reply mentions that the suggested paper does not cover the decomposition directly but may reference other relevant works.
- Participants recommend Bertschinger's review and Bardeen's paper as potential resources for a more detailed treatment of the topic.
- One participant acknowledges finding the Bardeen reference and expresses gratitude for the help.
- Ruth Durrer's book is mentioned as having a decent discussion on SVT decomposition within cosmological perturbation theory.
- A participant confirms having the book and finds it informative.
Areas of Agreement / Disagreement
Participants generally agree on the usefulness of the recommended references, but there is no consensus on a single definitive source that fully addresses the decomposition of perturbations.
Contextual Notes
Some references provided may not contain the specific details requested, and the discussion reflects varying levels of depth in the suggested materials.
Who May Find This Useful
Researchers and students interested in cosmological perturbation theory, particularly those looking for detailed resources on scalar-vector-tensor decomposition.
