PNpedia

This repository was created to make lengthy post-Newtonian results:

• easier to find, by putting all known results in one place
• more traceable, by collecting the various references in the literature in one place and flagging known discrepancies and typos
• more user-friendly, by including associated machine-readable files (in Wolfram language format)
• more reliable, by allowing users to endorse a result they agree with, and raise issues when typos or disagreements have been identified

Currently, the scope of this repository is complete, fully analytical, post-Newtonian results for the two-body problem in general relativity. Partial results, semi-analytical, many-body results or alternative theories of gravity are at this stage outside the scope of this repository.

The repository currently contains two main directories:

• Raw data, which is compendium of publications and the machine-readable post-Newtonian results associated to them. It is itself subdivided into two directories:
  • arXiv, containing preprints on arXiv, which is used by default
  • publications, containing peer-reviewed journal publications which either pre-date arXiv or have results that differ from the arXiv version
• Core post-Newtonian quantities, which aims to contain machine-readable files corresponding to the state of the art of post-Newtonian predictions for gravitational waveforms. It is structured using nested directories.

Alongside each machine-readable file (or collection of files), there should be a README.md file. This file should contain:

• the description of the physical quantity presented
• the notation used
• the reference(s) of the result, and potential known typos and disagreements
• a list of endorsers

Currently, the results are quite scarce, because it is intended to be a collaborative effort. Users are encourage to raise a pull request to:

• upload a missing machine-readable file
• endorse an available machine-readable file
• add or correct references or notations in the README.md files
• raise an issue if they have a disagreement with an available machine-readable file

Suggestions are also welcome.
