- Null space and kernel are taught as different concepts in different contexts. --Bkwillwm 21:45, 5 December 2005 (UTC)
Could someone explain how this is or is not the same as the kernel of a convolution? It seems to be different in that a convolution is linear yet in general only the zero vector maps to zero (I think). —Ben FrantzDale 15:47, 20 December 2006 (UTC)
can the editor of this article give me suggestions on how to make this picture consistent with the terminology of this article, thanks--Cronholm144 09:27, 31 May 2007 (UTC)
What is a Mal'cev algebra?
The article speaks of groups as being Mal'cev algebras, but the linked article Malcev algebra describes something that groups definitely are not, so what is a Mal'cev algebra in the context of this article here? 126.96.36.199 (talk) 19:13, 13 February 2013 (UTC)
- Surely additive groups are Mal'cev algebras when equipped withe the zero product. But Mal'cev algebra is too much a stub to decide what the editor did mean. I have tagged Mal'cev algebra as stub? D.Lazard (talk) 21:22, 13 February 2013 (UTC)
- Aren't Mal'cev algebras supposed to be non-associative algebras, which in turn are supposed to be modules? If a module needs to be an abelian group, how can a non-abelian group be a Mal'cev algebra? 188.8.131.52 (talk) 12:26, 14 February 2013 (UTC)
Kernel (Ring homomorphisms)
This section incorrectly states "It turns out that, although ker f is generally not a subring of R," but this is false (http://www.proofwiki.org/wiki/Kernel_is_Subring). I'll review the symbology carefully and update if it turns out that the article is in fact erroneous. 184.108.40.206 (talk) 01:10, 28 April 2013 (UTC)
