Talk:Engel's theorem

Dimension?[edit]

Header added. —Nils von Barth (nbarth) (talk) 08:20, 2 December 2009 (UTC)[reply]

In the lemma: is the dimension of V equal n? So the dimension of V_i is i?

Correct, but the article should note that. —- Taku (talk) 23:31, 16 October 2019 (UTC)[reply]

Style[edit]

I think the style of this article needs to be changed from a lovely lecture note/textbook style to a more terse dispassionate (life-less???) encyclopedic style. Also, the proof (which is not really long) should be given too. —- Taku (talk) 23:31, 16 October 2019 (UTC)[reply]

This is done; I hope I didn't diminish the accessibility too much. -- Taku (talk) 04:15, 17 October 2019 (UTC)[reply]

Naïve replacement?[edit]

"... the naïve replacement in Lie's theorem of "solvable" with "nilpotent", and "upper triangular" with "strictly upper triangular" ..."

Shouldn't it be the other way around? 85.167.200.57 (talk) 10:50, 29 January 2023 (UTC)[reply]

It looks ok to me; Lie’s theorem is about solvable Lie algebras and the same statement is false for nilpotent Lie algebras. —- Taku (talk) 14:21, 8 February 2023 (UTC)[reply]
