- diffhist Kernel (algebra) 09:45 +15 D.Lazard talk contribs (Undid revision 1291568716 by Gramix13 (talk) WP:NOTDEF means that the description needs not to be accurrate, but suffices to give an idea of the subject of the article. Here "concept in" is too vague. "Inverse image of 0" is correct, since for most readers, "homomorphism" means "linear map". If you disagree, take it on the talk page.) Tag: Undo
- diffhist Kernel (algebra) 07:39 +170 David Eppstein talk contribs (book citations need page numbers (best separately for each citation); also at least one citation is missing altogether)
- diffhist Function (mathematics) 03:48 +14 Goodphy talk contribs (→Partial functions: Slightly improved sentences for the section for partial functions.) Tag: Visual edit
- diffhist Kernel (algebra) 01:49 −15 Gramix13 talk contribs (Addressing WP:SDNOTDEF by using "Concept in [academic field]" format since there are two definitions for kernel depending on whether the structure is group-like (not to mention some groups don't have a "zero"), so it wouldn't be possible to accurately describe it with one definition while also avoiding jargon. I am open to discussion on what short description would be appropriate for this article.) Tag: Reverted
