what's T?[edit]

What the heck is T ? It looks as though it's a tetrad, but that's not exactly clear. ---Mpatel (talk) 12:14, 12 October 2005 (UTC)

T is the tangent space. — Preceding unsigned comment added by Okelekci (talkcontribs) 12:45, 2 February 2015 (UTC)


This article doesn't even attempt to define its topic; that would be a significant addition to the lede, if someone understands the topic well enough to define it clearly. The article also needs to be edited for tone (encyclopedia articles shouldn't contain the word "let's"), but that's a more involved fix.-Bryanrutherford0 (talk) 15:20, 21 May 2015 (UTC)

Its also bizarrely misnamed. tetrad=vierbein the tetra/vier refers to the four dimensions of space-time. I do not believe that geometers actually use this term, so it sounds like OR to me. Not sure. Certainly my books on Riemannian geometry do not mention it. This article should be a redirect to Tetrad formalism or to Frame fields in general relativity. Yucko. (talk) 22:41, 1 May 2016 (UTC)
