Proposal: add a tag for exponential families Rationale: I've asked at least a couple of questions now that I originally tagged with exponential-family, but each of these were edited to remove the tag. However, I think such a tag deserves to exist, because the concept of an exponential family is absolutely crucial to a number of topics in statistical ...

Proposal: Cancel the synonym complex-analysis and holomorphic-functions tags The holomorphic-function tag synonym was proposed in May 2016. It was approved in March 2019. (Information thanks to Martin Sleziak) Currently there are 6,698 questions about complex-analysis and 4689 questions about holomorphic-functions, it seems to me that would be ...

Proposal: Remove gre-exam, gmat-exam. These are meta tags with very bare-bones tag wikis. Furthermore, there aren’t any other tags for important math exams, i.e. the IMO or USAMO, so why should we make an exception for these two?

Please create the tag "realizability" for questions regarding realizability as the term is used by researchers like Kleene, Kreisel, Troelstra and also in more modern work on proof theory. Looking through posts that use the word "realizability", the term is sometimes used to refer to the term from proof theory, and sometimes in a seemingly colloquial manner ...

In the past week or so, I edited the tag-wiki for ENT to make it far less wishy-washy that primitive roots and quadratic residues were NT and everything before that in a typical class or textbook are ENT. (It's not quite easy vs. non-easy. For instance, Pythagorean triples are the solutions to a non-linear Diophantine equation and therefore fall under NT. ...

I believe that, although most of the times only one of the tags should be used, there are situations where both are appropriate. Consider, for example, this highly upvoted question. OP asks a question involving only prime numbers and elementary arithmetic: Definition: A positive integer $n$ is called interesting if it has a prime factorisation $n=pq$ with ...

Proposal: Merge probability and probability-theory tags. The idea behind having two tags is to divide basic and advanced probability questions, but it does not work and I believe it couldn't work. It is better to have single probability tag and use additional tags like combinatorics, measure-theory, etc. PS: Downvotes show that probability-theory is like a ...

Proposal: Rename collatz to collatz-conjecture. Although Lothar Collatz is most known for the $3x+1$ problem (the Collatz Conjecture), I don’t think their names should be used interchangeably. Furthermore, the latter tag has a more informative name. I posted this in the last Tag Management, but I only got a single upvote. I want to see what more people ...

Proposal: Create the tag eulerian-numbers. The Eulerian number $A(n,k)$ is the number of permutations in $S_n$ with exactly $k$ descents, and it is an important combinatorial object. Searching for "Eulerian numbers" is:q returns around 30 legitimate hits, which is a worthwhile number of questions to have a tag attached, in my opinion. I had also raised ...

The problem with this is many-fold: What if the new tags no longer fit the content after text edit ? What if wrong tags give the wrong impression of which version of the problem is wanted to be solved ? What happens if it looks like only a text edit is ongoing, but they then change or add tags ? How can we easily ensure mutual exclusion, without adding to ...

Proposal: rename teichmueller-theory to teichmuller-theory on main site. Reasons: I believe it is the correct spelling, barring the ü. (The only reason I can see why the tag might be spelled as it is is because the ü may change to a ue when it loses the accent, but I do not think this is the case.)
