• diffhist m Wigner's classification 10:09 +24 Starlighsky talk contribs (Added link.) Tag: Visual edit
• 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 Matrix (mathematics) 06:48 −1 Dedhert.Jr talk contribs (→Row operations: fix citation)
• 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

• diffhist Matrix (mathematics) 20:55 +1 Quondum talk contribs (some punctuation cleanup (placing outside <math> tags when inline, while preventing wrapping using {{tmath}}))
• diffhist Matrix (mathematics) 19:01 −2 Quondum talk contribs (typo)
• diffhist Matrix (mathematics) 18:55 −2,216 Quondum talk contribs (standardizing (almost) on {{sfnp}} for short references for uniformity of sfn format)
• diffhist Image (mathematics) 18:33 −55 NeilOnWiki talk contribs (→top: Replaced the use of "former notion" referring to preimage of a function, which I found confusing; removed superfluous link to "domain" of a function.)
• diffhist Matrix (mathematics) 18:00 −186 Quondum talk contribs (→Mathematical references: rm an unused reference that is also not mathematical in nature)
• diffhist Matrix (mathematics) 17:51 +32 David Eppstein talk contribs (use shortened references for Sylvester's collected papers)
• diffhist Matrix (mathematics) 13:58 −1 Quondum talk contribs (ƒ → f (replacing only curly ƒ))
• diffhist Matrix (mathematics) 13:56 +104 Quondum talk contribs (controlling wrapping of punctuation around <math> using {{tmath}}; consistent spacing of "m×n matrix"; reducing height of inline <math>)
• diffhist Number theory 13:41 +6 2600:4040:96a5:2600:906d:af41:f758:ea05 talk (→Elementary number theory)
• diffhist Hermann Weyl 13:40 +6 TheCosmos999 talk contribs (Continuing on the previous edit: inserted 'died' and 'm.' before year of termination of marriage and year of marriage respectively. It seems that previously his spouses had included with them their year of birth and death rather than the usual year of marriage and year of termination of marriage. And hence in implementing my changes, I have led to the lose of the years of birth and death of the spouses. Sorry for that.) Tag: Visual edit
• diffhist Matrix (mathematics) 13:34 +349 Quondum talk contribs (more uniform use of <math display="block">)
• diffhist Hermann Weyl 13:17 −1 TheCosmos999 talk contribs (In the INFOBOX, changed the year of his marriage with Ellen Bär from 1902 to 1950, making it thus align with the article body. Not sure if 1950 itself is correct but 1902 is unlikely; that would constitute polygamy.) Tag: Visual edit
