Topic: Green's open problem list

I saw this pdf linked on #510 and thought to post it here to give some attention to it. Some of the problems are repeated from the Erdos problems (like #510 being the same as 81 on the pdf) but a lot are new problems I hadn't heard of. I'm planning on adding each problem not covered by the Erdos problems as individual issues (when it isn't so late for me)

Moritz Firsching (Oct 07 2025 at 09:13):

very nice, I have been meaning to add a link to Green's list to the Readme as an example of dedicated problems list as well!

Anirudh Rao (Oct 08 2025 at 05:13):

I've added a couple of the problems as issues but unfortunately can't add the AMS tags as well. Also, wow creating all these issues is tedious. Massive kudos to @Moritz Firsching for how many Erdos problem issues he's created.

unrelated but erdosproblems #342 also linked this book that might be good to add more problems (though it needs institutional access) - https://link.springer.com/book/10.1007/978-0-387-26677-0

Note that as well as that book (Unsolved Problems in Number Theory), the series Unsolved Problems in Intuitive Mathematics has a second book Unsolved Problems in Geometry - https://link.springer.com/book/10.1007/978-1-4612-0963-8 - though since it never had a second edition, there would be a lot of work to figure out what's been solved since 1991 (the 1994 reprint has a brief note listing sections on which there had been "major progress", with no further details given).

I started with the first problem from Green's list, to establish a convention for the name of directory/namespace, https://github.com/google-deepmind/formal-conjectures/pull/899, reviews welcome

Anirudh Rao (Jan 08 2026 at 04:16):

Oh gosh, it's been 3 months and I hadn't raised the rest of the issues I promised... apologies! I've gotten up to 30 (FC#1565) now.

Btw, @Moritz Firsching I noticed that the AMS categories in the Green's open problems issues raised in October were removed so I didn't add them to the ones I had raised today. Do you have a preference of whether I should add them or not?

Yaël Dillies (Jan 08 2026 at 04:43):

Would be better to add them IMO

Anirudh Rao (Jan 08 2026 at 05:11):

Yeah, I had a thought around the mid-twenty mark that putting my opinion for what the AMS categories should be would be a little less work on maintainers' end.

Anirudh Rao (Jan 30 2026 at 22:27):

Never updated it here, but I raised issues for each of the open problems :slight_smile:
