A: Tag management 2023

Kevin DietrichProposal: Add tag dual-numbers. Although the dual numbers are a well-known hypercomplex number system, there is no tag for the dual numbers in SE (e.g. for this Question). As far as I've seen so far, there are no synonyms for dual numbers too.

new-tag The tag dual-numbers was created again. math.stackexchange.com/posts/4563339/revisions (The tag-info is empty.) It is the only new tag in February so far.

Q: How to take the square root of a dual number ($\sqrt{a + b \cdot \varepsilon}$ with $a, ~b \in \mathbb{R}$ and $\varepsilon^{2} = 0$)?

Kevin DietrichHow to take the square root of a dual number: $\sqrt{\Xi}$ with $\begin{align*} a, ~b &\in \mathbb{R}\\ \varepsilon^{2} &= 0\\ \varepsilon &\ne 0\\ \\ \Xi &:= a + b \cdot \varepsilon\\ \end{align*}$ My first attempt worked (at least I think so), but the second one came to nothing, but it seems to...

Pending tag synonyms: SEDE, list on site - when viewing this list, only the synonyms where users has score >=5 in the master tag are shown.
Five new synonyms were proposed in January.
Personally, I don't think those synonyms seem rather useful. For example, I can imagine that somebody want to search among the questions about geometric-series (rather than among all questions tagged sequences-and-series).
Looking at other pending synonyms, I am not sure about group-isomorphism $\to$ group-theory, either.
