Add links
From Wikipedia, the free encyclopedia

This page provides a list of all articles available at PlanetMath in the following topic:

08-XX General algebraic systems.

This list will be periodically updated. Each entry in the list has three fields:

  1. PM : The first field is the link to the PlanetMath article, along with the article's object ID.
  2. 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.
  3. 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.

It certainly comes up in my work fairly often, so I think it should be covered. It could also be merged with the graded algebra article Jtwdog 17:36, 3 October 2005 (UTC)[reply]
Ok, I copied it and made some minor revisions. Jtwdog 16:51, 20 October 2005 (UTC)[reply]
Actually, it is covered. Jtwdog 17:36, 3 October 2005 (UTC)[reply]
This is just a trivial fact that has no real significance. It appears to be an easy exercise from an algebra text. --Dan131m (talk) 04:04, 4 October 2009 (UTC)[reply]
This is an article defining "division" in a group by . There is also an elementary technical argument about groupoids. None of this has encyclopedic noteworthiness.--Dan131m (talk) 04:04, 4 October 2009 (UTC)[reply]
This is an "index of notations" like you might find in the front of a book. I don't know if there's a need for this or not. What do others think?--Dan131m (talk) 04:04, 4 October 2009 (UTC)[reply]
  • PM: biops, id=6385new! -- WP guess: biops -- Status:
This terminology doesn't appear to be in widespread use, as this page is the only mention of it that comes up on Google. (Could be a transliteration from some other language where the English word is different, though.) --Dan131m (talk) 04:04, 4 October 2009 (UTC)[reply]
This is just a proof that in a group. Adequately covered in group. --Dan131m (talk) 04:04, 4 October 2009 (UTC)[reply]
Dan131m (talk) 04:04, 4 October 2009 (UTC)[reply]
This article covers the categorical dual of a group, which is already defined and covered in Natural transformation. However it doesn't seem reasonable to force a beginning algebra student to learn category theory in order to learn what an opposite group is. For that matter, we need an opposite functor article as well, and several of the examples on functor could stand to have their own pages. Then it all needs linking together! I'll try to work on this a little. --Dan131m (talk) 04:04, 4 October 2009 (UTC)[reply]
