I did this. Sorry if this was inapproriate. I know it's not a good idea to edit many questions in a short time span, but I thought 10 was acceptable. With regard to the tag creation, however, I was not aware that it's inappropriate. I'll take note of the various opinions expressed here, for the next time I have such an idea. Note that (I believe) it was my ...

No, obviously not. The term "inequation" is not commonly used in English and in my experience its usual meaning is for statements with a $\neq$ sign, rather than inequalities that are to be solved as the tag creator seems to intend. In any case, there is certainly no reason to have such a tag to contrast with inequality, since the distinction is not sharp ...

A user created the sangaku tag then edited ten questions to include that tag, all in a short span of time. The user then created descriptions for that tag. As has been pointed out in the comments below, some users consider very inappropriate the editing of many old questions in a very short span of time, and some consider very inappropriate the addition of ...

Proposal to blacklist generalization Reason: It's overly broad and there is no real mathematical content in it. Also, the tag has been created and removed several times.

17

To avoid inequation being recreated, I have made it a synonym for inequality.

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?

There have been two comments of approval on this, and far more upvotes than downvotes, so I say go ahead! (In case you didn't check, I'm actually the OP. I'm posting this answer as a record of the feedback. Additionally, you can vote on this answer to express your opinion.)

I've reviewed quite a few of your edits over the last few days, and for a little while I thought you were just trying to increase your rep $2$ points at a time. I did eventually notice that you were engaged in retagging, but what made it hard to spot initially is: you tend to make small (and often unnecessary) changes to the body of the post, like ...

Questions that come from contests should give a source. MSE has relatively strict policy on questions from ongoing contests, and clearly citing your source helps to ensure that you won't run afoul of that policy. A source for a problem also adds valuable context–it gives answers some idea of what the motivation for the problem is, and can give a sense of ...

For example, I want to see all questions posted in sequences-and-series in September month of 2016. You can used built-in-search for this. The modifier created:2016-09-01..2016-10-01 returns only posts from September. (I have added one more day to be on the safe side - and also to make this easier to modify.) If you are interested just in one month, you ...

Resolved. The tags triangle and circle have been renamed triangles and circles, respectively. Proposal: pluralize triangle and circle Putting names of mathematical objects in their plural form is a common practice, e.g. polygons. We should treat "triangles" and "polygons" equally.

My personal thoughts: Even from the name, the two seem to carry the same intents (bear in mind, I've always heard "inequality" my whole life). The Wikipedia article doesn't seem to offer any information that would suggest the two are really two, distinct things, either. I don't claim to know why Wikipedia thought the two should remain separate, and I ...

Well, to start, we actually already do have a definition tag; however, in the case where you don't know the name of what you're looking for, it's probably better to use terminology or notation. Let's compare and contrast. A canonical question for definition would be something like I'm reading the paper A Treatise In Frustration (A. Gruber, Journal of ...

Resolved. generalizedeigenvector has been renamed generalized-eigenvector. Proposal: rename "generalizedeigenvector" to "generalized-eigenvector" Pledge originally initiated by WillG in this suggested tag wiki excerpt edit. I support this proposal since it's a common pratice to separate words with hyphens in tag names in order to increase readability, ...

Concerning the proposed [quantum-field-theory] tag: Not all "field theory" questions in physics are about quantum field theory. Questions about general relativity, Maxwell's equations, or the Navier-Stokes equations are all about "field theory", but they're about classical field theories, where there's no $\hbar$ in sight. Mathematically, the machineries ...

A tag for a book or an author would necessarily be a "meta tag": a tag that describes in which context the question was asked or what the direction of its answer should be. Meta tags are discouraged, see this thread. The primary reason behind this is that they do not help anyone to understand or assess the question any better, which is the main purpose of ...

Resolved. cauchy-riemann-equation is now cauchy-riemann-equations. Proposal: pluralize cauchy-riemann-equation Because… well, you know: there are two of them.

I suggest we rename fixedpoints to fixed-points for consistency.

Having posted the linked meta answer in the comments, perhaps I can give an answer. As @ArcticChar has mentioned, it's a convention to pluralize tags if possible, like cubic-equations, definite-integrals, etc. In such case, the tag name is used to refer to multiple objects of a category, instead of a single one. For example, definite-integrals is used for ...

I suggest to remove the tag calculus-identities. With the empty tag-info (and no suggestion for the scope of this tag in this discussion) the tag is very likely to be used inconsistently and it is rather questionable whether it is going to be useful. (It would be different matter if somebody suggested a reasonable guide for the type of questions where this ...

Resolved: planar-graph, bipartite-graph, chordal-graph, and signed-graph are now planar-graphs, bipartite-graphs, chordal-graphs, and signed-graphs, respectively. Proposal: pluralize planar-graph, bipartite-graph, chordal-graph, and signed-graph. (To match random-graphs, directed-graphs, cayley-graphs, infinite-graphs, and hypergraphs, as well as the ...

Resolved: euler-method has been merged into eulers-method, a synonym created, and tag wiki updated. Proposal: synonymize euler-method with eulers-method Notice that they are indeed different tags, as the former has user guidance, the latter doesn't. But they are essentially the same thing, i.e. a numerical method to solve first-order first-degree ...

So far it seems from the votes and comments lean towards separating dimension theory in analysis/topology from dimension theory in algebra. Let me just add one additional suggestion. Suggestion. Do not put questions about dimension theory in linear algebra under the same tag as dimension of rings/modules. Whether or not a tag for dimension in the sense of ...

The tags on a question are not only to categorise the content of questions, but also to indicate the level of specificity of the asker's knowledge. A less specific tag tends to indicate less specific knowledge. Consider, for example, the tags calculus and real-analysis. These subjects have a very large overlap. Within this overlap, the primary difference is ...

Resolved; accessible-categories and locally-presentable-categories are created Proposal : tag(s) for accessible and locally presentable categories A couple months ago someone created (among others) the tags locally presentable categories and accessible categories, but they were removed. Now this is not really my specialty, but I think these tags could be ...

Resolved. continuoustime was removed. Proposal: remove "continuoustime" tag The tag continuoustime has zero questions currently.

Partially resolved. tqft has been synonymized into topological-quantum-field-theory. A consensus has not yet been reached on the name change to topological-quantum-field-theories. Proposal: rename "topological-quantum-field-theory" to "topological-quantum-field-theories" and synonymise it with the tag "tqft" An old question of mine recently had a couple of ...

Resolved: topological-data-analysis has been created. Synonyms include tda and persistent-homology. We need a tag for topological data analysis. It is a rapidly growing field, so there will be more and more posts about it. Currently, questions about TDA come up under the tags algebraic-topology, homology-cohomology, data-analysis, category-theory, and a ...

Resolved (The tag now has the longer name.) I suggest to rename differential-equations to ordinary-differential-equations. (Now that the limit for the length of tagnames is 35 characters, the latter is a possible name for a tag.) Both the tag-excerpt and the tag-info for (differential-equations) explicitly say that it is for ODEs and not for PDEs. And ...
