Recently a tag has been created

https://math.stackexchange.com/questions/tagged/converse-of-propositions

There is no description and only 3 questions by the same user. I think this tag should be closed/deleted. I do not see any options of doing it, maybe because I do not have sufficient reputation.

  • $\begingroup$ It might be a meta-type tag, but I could see a use for a tag called "generalizations" which could be appropriate in this situation. This could be for questions asking for generalizations of a result or if the converse of a result holds. $\endgroup$ – Michael Burr Feb 27 '17 at 22:01

    $\begingroup$ @MichaelBurr how would this tag help to classify and to structure the content of the site? Being a generalization or converse of "whatever" is about as unspecific as it gets. $\endgroup$ – quid Feb 28 '17 at 10:22

    $\begingroup$ @quid Your point is well-taken. Looking through the list of tags, I'll point out the "examples-counterexamples" tag as something in the same vein. "Examples-counterexamples" isn't necessarily specific to a topic, but characterizes the type of question. "Generalizations" could also be of a similar type of tag. For example, a question of the form: "(something) holds true for a finite dimensional vector space, what happens in an infinite dimensional vector space? The standard proof fails, but is there another way?" This, of course, may not be a good idea, but that's the point of meta. $\endgroup$ – Michael Burr Feb 28 '17 at 12:36

    $\begingroup$ @MichaelBurr on the one hand, I think ex-counter-ex is not all that good a tag either. On the other hand, for vague reasons hard to make precise in abstract, I feel that counterexample is still somewhat more specific than generalization. By way of example, there is a fairly well-known book "Counterexamples in topology" and I think such things exist for other subjects too. Even not knowing the book I'd feel the title conveys some quite concrete information what to expect. However, I'd have a hard time to imagine what something titled "Generalizations in topology" might contain. $\endgroup$ – quid Feb 28 '17 at 13:15
  • $\begingroup$ @quid I will take some time to think about your response. I am familiar with "counterexamples in topology," but I think that "generalizations in topology" is not a fair example to use because topology is such a fundamental topic in mathematics. $\endgroup$ – Michael Burr Feb 28 '17 at 13:27
  • $\begingroup$ This tag would've been appropriate for my question here: math.stackexchange.com/questions/1317724/… $\endgroup$ – Kaj Hansen Mar 10 '17 at 2:57

I agree that this tag should be deleted it is clearly a meta tag.

To delete a tag that only appears a few times just remove it from every question. It then, being empty, will be auto-deleted within a day.

There is no dedicated way to delete a tag for users. For larger tags bring up the subject in this thread: Tag management 2017 (or the then current version).

Network-wide moderators can actually delete tags, and per-site moderators can at least replace at once and without bumps all occurrence of a given tag by a different one (which is sometimes sufficient to get rid of an undesirable tag).
