Someone anonymous has deleted a paragraph at red herring principle on non-associative algebra. This seems a bit strange. I am no expert on those beasties but although non-associative algebra includes the study of Lie algebras etc., amongst them are the modules and it seems to me that a module (with trivial multiplication) considered as a Lie algebra is an associative non-associative algebra! The query by Toby further down the entry is relevant but if we assume ‘non-unital’ as well (and that is sometimes done) there is no problem.
There was no post to the Forum. The IP is 2.40.78.132. which is in Trieste it seems.
Should the paragraph be reinstated?
Thanks for watching out for this!
I suppose one could have different opinions on whether “Lie algebra” is an “algebra as used in linear algebra”, and maybe that paragraoph could be tweaked a bit. But what worries me here is that people remove material without any announcement here. We’d have enough signposts on the HomePagethat advice not to do that, I would think. What else could we do?
I have to run now. But if somebody finds the time to re-instantiate that paragraph and maybe addd a bit re Lie algebras etc., that would be good.
Your worry mirrors mine, hence my post here.
I have rolled it back.
I rewrote that paragraph a bit too.
I was thinking of adding a point
but I’m not certain that it is an instance of the red-herring principle, but also not sure it falls under the ’non-examples’ section. Any thoughts?
I wouldn’t classify that as either.
