Advice to stub expanders (probably myself, when I find time)[edit]

general first, specific later
- n dimensions first, 1+3 later
nontechnical first, technical later
- mention role of Lluis Bel in first paragraph
- in later technical paragraphs:
  - relate to matrix decomposition in MTW exercise
  - explain physical interpretation in gtr in a frame of the three pieces
  - make sure to contrast roles of frame and congruence in interpretation; choice of frame field adds additional geometric structure to the congruence
add good citations at the end (original paper by Bel, MTW, plus some useful eprints on arXiv) in standard WikiProject GTR format

Students beware[edit]

I created the original version of this article and had been monitoring it, but I am leaving the WP and am now abandoning this article to its fate.

Just wanted to provide notice that I am only responsible (in part) for the last version I edited; see User:Hillman/Archive.

I emphatically do not vouch for anything you might see in more recent versions.

Good luck in your seach for information, regardless!---CH 22:28, 30 June 2006 (UTC)[reply]

Redirecting all sub-articles into this one.[edit]

This article, and the 3 tensor sub-articles, were all created in 2005 and have been mostly unmaintained since. The 3 sub-articles each have only a single sentence, no references, no further reading, and convey no information that can't be conveyed in this article. This article is, in fact, still a stub. As these articles are unmaintained, outside of grammar and formatting fixes, I believe no one will object. I will use the blank-and-redirect tactic from WP:Redirect to redirect all 3 pages here. Please let me know if you have objections. Footlessmouse (talk) 06:41, 17 August 2020 (UTC)[reply]
