I write an expository column for the 𝘕𝘰𝘵𝘪𝘤𝘦𝘴 𝘰𝘧 𝘵𝘩𝘦 𝘈𝘮𝘦𝘳𝘪𝘤𝘢𝘯 𝘔𝘢𝘵𝘩𝘦𝘮𝘢𝘵𝘪𝘤𝘢𝘭 𝘚𝘰𝘤𝘪𝘦𝘵𝘺. A while back I wrote about the polyhedron shown below. My column was corrected by two referees and accepted. I submitted it to the arXiv - the main online archive of math papers. I submitted it to their section for "history and overview", because the ideas were not new. But someone at the arXiv added the section "combinatorics". I thought this was a weird choice.
More recently I wrote a column about the moduli space of acute triangles. Again it was corrected by two referees and accepted. I again submitted it to the arXiv, choosing the section "history and overview". This time some sort of AI system recommended that I submit it to "algebraic geometry". I'd never seen that before! I followed its suggestion and removed "history and overview".
Now my arXiv submission has been "on hold" for 9 days. I know some people who are persona non grata with the arXiv, whose submissions are put on hold endlessly with no explanation. Am in trouble, or are the folks at the arXiv just being slow? I'm trying to decide when to email them.
Here are the columns, in case you're curious:
• The icosidodecahedron, https://arxiv.org/abs/2309.15774
• The moduli space of acute triangles, https://math.ucr.edu/home/baez/triangles.pdf
