Since we are already discussing tagging and retagging, what is a suitable tag for algebra over a field?
I've already asked this, without getting some definitive answer: chat.stackexchange.com/transcript/message/2514751#2514751

How many questions do we have that would fall under this potential tag?

@JM It's not easy to say, but I stumbled upon some such question when retagging questions having tag algebra.
Maybe a few from this google search google.com/…
Some of these look suspicious too math.stackexchange.com/search?q=[algebra]+%22A+over+a+field%22
This one math.stackexchange.com/questions/20829/degree-of-an-algebra is an example of such questions, which has only algebra tag.

Okay. Now for the naming... algebra-over-a-field is way too long. abstract-algebra is alright, but a rather wide umbrella...
Martin Sleziak

Some of such questions are indeed tagged abstract-algebra: math.stackexchange.com/questions/37581/… math.stackexchange.com/questions/43197/…

@JM Yes, e.g., ring theory is a subset of abstract algebra, but we do have a ring-theory tag.

Testing: abstract-algebra.
Ok, I've learned a new thing today. Hopefully, it will not be the only one...

...and field-theory, well...

@MartinSleziak I would say it also depends on what you want to do with these algebras. Maybe modules-algebras would encompass what you're looking for. For example ring-theory, representation-theory contain questions that would fit that tag (and yours).

Well, I will bring this up again if I won't be able to retag some question correctly.
I did not want to create new tags, I guess two new tags are enough for one day...
t.b.

I see :) I share that feeling that doing something about it would be useful (maybe even necessary), however I couldn't come up with a tag proposal that I really liked.

BTW I was browsing new tags and noticed this derivatives. (It's 4 days old.)
When new questions concerning derivatives come, should we add this tag?
(This is my last question about tagging for today, I promise.)

@MartinSleziak I guess it's about time. calculus has way too many "differentiate blabla" questions...
On the other hand, do we count questions on partial derivatives? Jacobians, gradients, and Hessians?
t.b.
t.b.
multivariable-calculus

@JM ok, When I see a new question in that direction, I'll add the tag.
J. M.
J. M.
@tb Wide umbrella. ;)
t.b.
t.b.
well, combined with derivatives...
J. M.
J. M.
Okay, so yes, the new tag can apply to any number of variables? :)

And we also have vector-analysis already.
J. M.
J. M.
...and I suppose we could also throw in some of those Gâteaux and Fréchet questions we have?
t.b.
t.b.
(whoever came up with that ghastly term in the distant past, we're not analyzing vectors there, as far as I can tell :))
J. M.
J. M.
Heh. Too late to rename that section, I think.
t.b.
t.b.
@JM I recently eliminated a new frechet-derivative because I felt it was overly specific, but apparently there's quite a bit of confusion there.
(funny, the [tag:...] doesn't like diacritics :))
:)

@tb Oh, I saw that before it was nuked... :)

@JM I plea guilty of that. I gotta go for a while, maybe we'll talk again tomorrow morning (for you), afterwards I'll be gone for about a week. So, see you later or next week.
J. M.
J. M.
That long, huh? Have a good one. See you!
