Q: Genericity of equivariant embeddings

geometricKI'd like to ask an equivariant version of this question. Let $M$ be a closed manifold equipped with the action of a compact Lie group $G$. By the Mostow-Palais embedding theorem, $M$ can be embedded equivariantly into $\mathbb{R}^n$ for some $n$, where $G$ is realized as a subgroup of $GL(n,\math...

The tag genericity has only one question at the moment, it was created in February 2020.
Feb 16 at 13:52, by Martin Sleziak
new-tag A new tag genericity was created, including a tag-excerpt and a a tag-wiki.
The tag-excerpt:
> Questions about notions of genericity in computability theory/descriptive set theory. Not restricted to the 'standard' partial order producing $\alpha$-generics. Use the forcing tag for set-theoretic forcing.
The tag-wiki for genericity:
> Use this tag for questions involving about notions of genericity in computability theory/descriptive set theory, e.g., $\alpha$-generics for $\alpha$ an ordinal notation, $\Sigma^1_1$-genericity as well as genericity relative to other partial orders in computability or descriptive set theory. Use the forcing tag for set-theoretic forcing.

@WlodAA I see that you have created the (peano-curves) tag. It might be useful to create also the tag-wiki or at least the tag-excerpt. It might help other users to use the tag correctly. (This is probably not a problem here, since the tag name seems to be descriptive enough.) Another reason is that the tags used on only one question are automatically deleted after certain time unless they have a tag-wiki. — Martin Sleziak 35 secs ago
peano-curves was crated back in March: chat.stackexchange.com/transcript/10243/2020/3/25 (So it is getting close to six months - which is when the tags with a single occurrence are pruned.)

specific-question meta Perhaps on-topic could be added to: Ron Graham (1935-2020), and MO “memorial” questions?
The question here is (among other things) whether such posts are suitable on MO. So maybe the tag (on-topic) could be suitable for this question? — Martin Sleziak 39 secs ago

Q: Ron Graham (1935-2020), and MO "memorial" questions

François G. DoraisAs you may know, Ron Graham passed away on July 6, 2020. In the past, when a famous mathematician passes away, many community members feel that they should be remembered on MathOverflow in some way or another. For obvious reasons, such memorials need to be carefully designed to honor the life and...

Unless opposition I'll edit this question removing reference to a particular obituary (currently I'm uncomfortable with this question, while I think the discussion is necessary). — YCor 3 hours ago
