Affine symmetric group

Affine symmetric group is at FAC and would benefit from someone familiar with this subject inputting on the sourcing. See the bottom of the page here. Thanks. Gog the Mild (talk) 18:03, 17 August 2023 (UTC)

To be explicit about what is requested: in the section Source review, Jo-Jo Eumerus has marked six footnotes as needing to be checked by a mathematician as to whether the material to which they are attached is appropriately sourced (the footnotes support the article, the content of the sources is correctly represented in the article, the sources are reliable, etc.). Any help with this would be greatly appreciated. --JBL (talk) 20:40, 20 August 2023 (UTC)

Smith–Volterra–Cantor set

I have a concern about whether the name "Smith–Volterra–Cantor set" is in fact standard. I posted a note at talk:Smith–Volterra–Cantor set#Naming, but it's a low-traffic article and I don't really know whether anyone will notice it. Anyone who can contribute, it would be appreciated. --Trovatore (talk) 20:24, 21 August 2023 (UTC)

Italics on Pentagramma mirificum

Should the title of this article be italicized? I forgot if every Latin term should be so, according to the guidelines.--ReyHahn (talk) 14:51, 25 August 2023 (UTC)

According to WP:ITALICTITLE, yes: Use italics when italics would be necessary in running text; for example, ... foreign phrases are italicized both in ordinary text and in article titles. —David Eppstein (talk) 04:36, 27 August 2023 (UTC)

It appears that it is used in italics in the article so I will carry out the italicization of the title. Be free to revert otherwise.--ReyHahn (talk) 12:29, 28 August 2023 (UTC)

Lead image in Tree (set theory)

I am having a dispute with an editor of Tree (set theory) who insists on adding a lead image that depicts a graph-theoretic tree, not a set-theoretic tree (the difference is that in graph-theoretic trees every node except the root has a parent, and following parent links will eventually reach the root, but in set-theoretic trees the ancestors of any node can have arbitrary well-orderings in which not all elements have a parent). Additional informed opinions would be very welcome at Talk:Tree (set theory) and in editing the article (or maybe finding or creating a more appropriate lead illustration). —David Eppstein (talk) 04:32, 27 August 2023 (UTC)

Emmy Noether

Algebraically inclined editors may wish to look at Talk:Emmy Noether#WP:URFA/2020, where there is discussion of whether Emmy Noether meets current featured article standards (and if not, what must be improved). — Bilorv (talk) 17:36, 28 August 2023 (UTC)

So I don't have anything to add to that as a discussion per se but are there particular tasks that if someone did them it would be helpful for ensuring that the article stays at FA? --JBL (talk) 17:37, 31 August 2023 (UTC)

COI edit request at Probability box

A COI editor has made a request for information to be added to the Applications section of this article. The requesting editor appears to be the author of the reference they are hoping to apply to the requested addition to that section. Unfortunately, Space Trajectory Optimization Asteroid Impact Monitoring State Estimation is not independently notable (nor for that matter, are many other items in the Applications section). Thus, I was hoping someone more mathematically inclined could have a look? Thank you very much for any help on this. Regards,  Spintendo  01:01, 31 August 2023 (UTC)

Hurwitz space

I've promoted this from AFC. Its seems genuine and well referenced. I'm not a mathematician so I looked up some references to confirm its existance and to determine if there was an article on Wikipedia on the subject, but doesn't appear so. scope_creep^Talk 06:05, 31 August 2023 (UTC)

It's definitely a real thing; I am not an expert in this subject, but I am inclined to agree that it is not duplicative of existing content (at least that I could find). Thanks for promoting it. --JBL (talk) 17:22, 31 August 2023 (UTC)

Where is the right place to feature request support for LaTeX macros/packages?

Wikipedia's Math/LaTeX syntax doesn't support the \rlap, \llap, \clap macros. I'd like to request feature support for these macros (perhaps in mathtools package? I'm not sure). These macros are incredibly useful to pad/align equations and terms, especially when the equations are in a column in a table and can't rely on a single align block. For instance, compare the table at Inverse trigonometric functions#Solutions to elementary trigonometric equations with its layout/markup prior to my edits. I had to use a lot of \;\,\qquad -style spacing. But instead, I could have used a more "semantic" spacing à la the following, if \rlap were available (ignore the align block; I used that in an external Latex editor to help me get the alignment):

\begin{align*}
\theta &= \rlap{(-1)^k}\phantom{(-1)^k\;}\rlap{\arcsin(y)}\phantom{arccos(x)} + \rlap{}\phantom{2\,}\pi k \\
\theta &= \rlap{(-1)^k}\phantom{(-1)^k\;}\rlap{\operatorname{arccsc}(r)}\phantom{arccos(x)} + \rlap{}\phantom{2\,}\pi k \\
\theta &= \rlap{\pm}\phantom{(-1)^k\;}\rlap{\arccos(x)}\phantom{arccos(x)} + \rlap{2}\phantom{2\,}\pi k \\
\theta &= \rlap{\pm}\phantom{(-1)^k\;}\rlap{\operatorname{arcsec}(r)}\phantom{arccos(x)} + \rlap{2}\phantom{2\,}\pi k \\
\theta &= \rlap{}\phantom{(-1)^k\;}\rlap{\arctan(s)}\phantom{arccos(x)} + \rlap{}\phantom{2\,}\pi k \\
\theta &= \rlap{}\phantom{(-1)^k\;}\rlap{\operatorname{arccot}(r)}\phantom{arccos(x)} + \rlap{}\phantom{2\,}\pi k \\
\end{align*}

Where do I lodge a feature request? Or should I lobby for it here first, and get community support for it? What's the process for Latex package addition? Thanks.  — sbb (talk) 17:53, 31 August 2023 (UTC)

You would want to use the Phabricator bug tracking system using the math tag. See https://phabricator.wikimedia.org/project/view/130/ There are other feature requests for extended maths syntax there. Don't expect a quick resolution, though.--Salix alba (talk): 18:13, 31 August 2023 (UTC)
