Wikipedia:WikiProject Mathematics/PlanetMath Exchange/83-XX Relativity and gravitational theory
This page provides a list of all articles available at PlanetMath in the following topic:
- 83-XX Relativity and gravitational theory.
This list will be periodically updated. Each entry in the list has three fields:
- PM : The first field is the link to the PlanetMath article, along with the article's object ID.
- WP : The second field is either a "guessed" link to a correspondingly named Wikipedia article, produced by the script which generated the list, or one or more manually entered links to the corresponding Wikipedia articles on the subject.
- Status : The third field is the status field, which explains the current status of the entry. The recommended status entries are:
| Status | means PM article |
| N | not needed |
| A | adequately covered |
| C | copied |
| M | merged |
| NC | needs copying |
| NM | needs merging |
- Please update the WP and Status fields as appropriate.
- if the WP field is correct please remove the qualifier "guess".
- If the corresponding Wikipedia article exists, but the link to it is wrong, please fix the link.
- If you copy or merge an article from PlanetMath, please update the WP and Status fields for that entry.
- If you have any comments, for example, thoughts on how the PlanetMath article compares to the corresponding Wikipedia article(s), please place such comments on a new indented line following the entry. Comments of this kind are very valuable.
Don't forget to include the relevant template if you copy over text or feel like an external link is warranted
- {{planetmath|id=|title=}} for copied over text
- {{planetmath reference|id=|title=}} for an external link
See the main page for examples and usage criteria.
One can use the web-based program Pmform to convert PlanetMath articles to the Wikipedia format. As a side benefit, this tool will place the PlanetMath template for you.
83C05 Einstein's equations (general structure, canonical formalism, Cauchy problems)
edit- PM: Einstein field equations, id=6757 -- WP guess: Einstein field equations -- Status: A
- WP article includes everything in the PM article and more. Ben Cairns 16:13, 11 April 2006 (UTC)
- PM: Ricci tensor, id=6758 -- WP guess: Ricci tensor -- Status: NM
- No expert on the subject but there seems to be more in this PM article than can be found in the WP article. Ben Cairns 16:13, 11 April 2006 (UTC)
