I am against this synonym. Although many discrete math problems are also combinatorics problems, and depending on your definition it might be that all combinatorics problems are discrete math problems, they don't mean the same thing. There are many many discrete mathematics problems that are not combinatorics problems, such as problems in elementary number ...
Its days are numbered, starting today. You've voted, and while a little controversial, we'll support your decision. What remains is just the 'final arrangements', so to say.
We'll need some preemptive cleanup
Things with the homework tag applied to them do tend to have some issues. Take a stroll to the end of the very long tail - use your flags and close ...
In the question I have mentioned several possible actions. To me the most reasonable seem to be creating a synonym betting $\to$ gambling. (I.e., with (gambling) as the master tag.)
In this way when somebody asks a new question and wants to add a tag, if they start typing "betting" in the tag field, they will be shown the synonym.
I am posting this as an ...
Resolved: The tag is now deleted
I think java-applet should be removed.
Resolved: The synonym is approved.
double-factorial should be a synonym of factorial. Link to the suggestion.
The double factorial can easily be expressed in terms of factorials. In fact most questions currently tagged double-factorial involve some rewriting to factorials and then using properties of the factorial. Also, currently, 7 out of 9 questions ...
Proposal: Changing the tag name to something more descriptive might make it clearer to the user what the tag is intended for and thus incorrect use will be less likely. (And thus reducing the frequency of this problem in the future.) I would suggest divergence-vector-calculus or divergence-vector-field or something similar.
This is the same suggestion as ...
I don't have much to say about what is going to happen. But I do want to point out something about what is going on. This point was sorta brought up by another user, but the answer was deleted.
There are people currently removing the homework tag manually from questions. But I have seen some users removing it from "famous" questions which are old, and ...
I don't understand intended usage of integers. Perhaps it should be either made a synonym of elementary-number-theory or just removed.
(Tag-wiki explains things like «The letter Z comes from the German word "Zahlen" which means "numbers".» but doesn't help much.)
Upd. Many questions tagged 'integers' are obviously in need of manual retagging, I'm afraid.
Apparently we have tags cohomology-operations and cohomological-operations, with 10 and 20 questions respectively (including 1 with both), different tag excerpts, and a tag wiki for the first one only. I don't know the topic very well, but the excerpts seem to describe essentially the same context. Should these tags be merged?
Summary Thread for Implemented Changes
(Please do not edit this answer unless you are a moderator. All proposed changes should be added as new answers to the question. Users with 10K+ reputation will still be able to see the original dates of proposals and implementations.)
One should also note that there exists a page on the StackExchange platform ...
I don't care too much for homomorphism.
It lumps together questions about homomorphisms in different algebraic structures, which work quite differently, in general. Therefore, few users will find it convenient to ignore or favorite.
The tag for each of these algebraic structures necessarily includes questions about homomorphisms between those ...
In general, yes
The use of overly-specific tags is to be discouraged.
This is because that every question can only have five tags, and that tags serves a function of helping organisation and finding of questions.
Personally, in this specific case, I think the tag is not very useful.
But I would point out that there also exists the graph-isomorphism; ...
Resolved: The tag is now deleted
I think hardware should be removed.
Out of the 9 questions, I think there are only 2 or 3 with the right tag. Most of the other questions use hardware when math-software or neither should be used. I think this will need some manual retagging.
Exactly how many active users do we have? I would suggest that 156 is a tiny fraction.
I've been an active user of the site for a couple of years and had no idea that this discussion was taking place. I find it questionable that a discussion with a different web address (meta) can impact on the ordinary site.
It seems a little like me getting a few of my ...
Resolved. The tag span is now synonym of linear-algebra.
I also suggest a removal of the tag span. It isn't really that meaningful to warrant its own tag. Often in linear algebra, we are considering spans of vectors implicitly. If the tag was being applied correctly, a large portion of the questions concerning linear algebra would be tagged span.
I consider the tag even-and-odd-extensions too specific to be really useful. (Having too specific tags applicable only to very narrow class of questions can cause problem since there are only five spots available for tags.)
My suggestion is to create a new tag even-and-odd-functions. This tag is at least slightly more general. It might be potentially useful,...
Let's at least implement this for very popular arXiv-style tags (ag.algebraic-geometry and such) — it's useful both for migration and for (admittedly rare) visitors from MO asking questions here.
On the other hand, creating synonyms for numerous small tags (like recurrences used for less than 50 questions on MO) seems (to me) to be an overkill.
