Posts from new users (those with fewer than 5 posts) are put into a moderation queue and will not appear publicly until approved.
Please keep your posts on topic and mathematical.
Comments prepared with the assistance of AI are permitted, provided (a) this is disclosed, (b) the contents (including mathematics, code, numerical data, and the existence of relevant sources) have been carefully checked and verified by the user themselves without the assistance of AI, and (c) the comment is not unreasonably long.
Low-value comments that I judge to be written by AI may be not shown and/or deleted at my discretion.
Long detailed formal proofs of problems should not be posted as comments; if you have such a proof (and have checked yourself, as a human, that it is correct), you are encouraged to write it up as a preprint in the traditional fashion and submit it to a journal. There is no firm rule about what is 'too long/detailed', and this is heavily context dependent.
