there seems to be 3 classes of questions with differential: (1) ones about infinitesimal constructions, (2) ones where the word differential can be replaced by one of "derivative" and "differential form", (3) ones where the tag differential was meant to be differential-geometry or ordinary-differential-equations or some such thing

@ronno Differentials are objects which come into their own in the study of smooth manifolds. I don't think that the existing tag wiki is all that great, but there is something distinct about differentials (vs derivatives).

As I posted in the retagging question, I want to improve the state of the differential tag and the suggestion seems to be positively received. Is this a good place to discuss what exactly should be done and how to go about it?

@Feeds The proposed tag "fractional-differential-equations" has drawn three upvotes and no downvotes, so a positive response by common standards. I see there are forty existing Questions that combine tags fractional-calculus and ordinary-differential-equations, the natural alternative. So perhaps there is the necessary quantity of posts to connect up.

Q: Fractional-Differential-Equation tag

Fractional Differential Equations are becoming very important. I propose to the community to consider it a tag, and also its abbreviation FDE.

I don't think that I, personally, am opposed to such a tag, but I also don't see it as being terribly useful. :/

I removed the stirling-formula tag, and left a comment directing the asker to the tag management thread, and to this room.

From the above, I'd say that the people who participated in that discussion on Meta Stack Exchange consider not synonymizing those two tags as a better option.

Xander Henderson

Nov 23, 2022 14:09

@MartinSleziak I think that this seems like a reasonable meta discussion. I think that my preference would be to have bookmarks be made a synonym of saves, since the bookmarking system has been superseded by the save system, but I can't say that I have a strong opinion.

The background: I think that convexity-inequality is unnecessary. The tag wiki shows that it was created for a very specific property of convex functions. But apparently it is abused frequently, e.g. in this recent question, for questions about convex functions involving some inequality.

Martin R

Oct 26, 2022 18:01

I think one should get rid of it, and replace it by convex-analysis where needed. Or make a tag synonym? But I don't know if it worth the effort to post and discuss this on Meta :)

Can someone tell me how to search for questions which are not tagged with a specific tag? Concretely, I want to find out how many questions are tagged with convexity-inequality but not with inequality. I could not find that information in math.stackexchange.com/help/searching.

Martin Sleziak

Mar 16, 2020 10:23

My personal recommendation would be to make an answer in the Tag management thread - to see what other people think about the new tag.

When I recently checked my sugested edit queue, it contained three different edits where the tag "solid-geometry" was added to a post. I didn't know this tag and the description does not really help - it claims to be about all 3D Euclidean space, but references a Wikipedia page that claims it's about 3D solids (and which has a lack of citation warning). What does it mean? Should the explanation of the tag (that isn't used that often) be improved?

I mean "inner-product" or "inner-products" would be just as good.

The word "dimension" in mathematics has a lot of meanings in different fields, and these various notions of dimension don't necessarily have a lot in common. A dimension tag seems like a very bad idea---totally useless.

specific-question meta Should this be discussion rather than support? Valid edit suggestion to a post was rejected.

It's ultimately your call, but I'd wait a bit. IMO opinion there is no urgency - whether the tag is created today or a week later, there's not much of a difference.

@MartinSleziak @MichaelAlbanese I think that is something which could be brought up in the tagging thread. While this seems like a good idea, it is way outside my area of mathematical expertise, and I would like to see some community input about whether these tags should (or should not) include the word "groups".

Michael Albanese

Apr 6, 2022 14:04

I think it would make sense to change hopfian-groups to hopfian to be consistent with co-hopfian. Alternatively, co-hopfian could be made co-hopfian-groups. Not sure which of the two would be preferred. Regardless, how can I suggest such a change?

Michael Albanese

Apr 6, 2022 13:28

I have decided to create the co-hopfian tag. Is my impression correct that capital letters are not to be used in tags?

Martin Sleziak

Apr 6, 2022 10:51

Maybe I should say that it is nice that there are people who try to ask (somewhere - in chat, on meta, ...) before creating a tag. There is certainly a lot of users who simply create tag - without considering whether it is a useful tag, whether such tag has already been removed before, etc.

Michael Albanese

Apr 6, 2022 08:38

There is already hopfian-groups for groups which are not isomorphic to a proper quotient of themselves. I was wondering if it is worth creating a tag for co-hopfian groups which are groups which are not isomorphic to a proper subgroup of themselves.

Martin Sleziak

Apr 6, 2022 04:17

BTW you can used [tag:examples-counterexamples] examples-counterexamples or [meta-tag:support] support both in the posts and in chat. (The advantage being that it is visually distinguished as a tag and that one gets a link.)

At least for some of them, propositional-calculus seems to be a better suited tag than boolean or boolean-algebra.

I think the backpropagation tag should be merged to the AI. And when someone ask, could be AI+multivariable calculus

Martin Sleziak

Still, the question remains. For verification question we have proof-verification and solution-verification as synonyms. Should there be a tag called alternative-solution - in addition to algernative-proof?

@XanderHenderson I have no complaints about having a proper discussion about this. It is very hard to convince me that new tags are needed, but it's not impossible.

Q: If there's a "short" question, to some extent, why not to edit properly with the proper tags?

Whether the question actually needs more context, for some users, shouldn't the question be properly tagged? In a more extreme context, suppose the question is a psq, those shouldn't be properly tagged? e.g. it's about analysis, why to tag the question with algebra?

@MartinSleziak economics and mathematical-economics should be synonyms, or the latter should be eliminated (e.g. notice there is no tag for "mathematical finance" and all such questions fall under finance)

in CRUDE, 37 secs ago, by Xander Henderson

I have been working for the last month to either retag or delete every question which is tagged with only the tag tranformation; I don't think that this tag is at all useful (it was discussed in the tagging chatroom towards the end of last year). The above questions are the last ones---I think that they should all be deleted, but if anyone can come up with better tags, that would be good, too.
