To get Mathematicians intersted in using #nostr you need to make #Math Markdown Available on the platform and displayable in #nostrclients.
This was what made me choose gitlab a few years ago over github for the #webcats forum. https://web-cats.gitlab.io
Math Markdown is why mathematicians are happily chatting on https://categorytheory.zulipchat.com and it was the first thing they added support to for https://mathstodon.xyz .
Unicode can go some way ∀m: Man ∃w: Woman Loves(m,w) but not all the way.
Of course I think markdown would be quite helpful for normal posts too. Hey Twitter has bold, italic, bullets, and stuff like that now...
