NOTE: I did try again to prove the Löwenheim-Skolem theorem.
My new question is here.
What are the rules and guidelines for attempting to prove the same theorem again?
Some notes specific to my situation:
I've been trying to learn model theory off and on for a little while. The way that I've decided to do this is to pick foundational results and try to come up with proofs of them without consulting the textbooks I'm using, except for definitions.
The last time I tried to do this, my proof attempt was invalid, but I learned something useful from the commenter.
I want to try again fairly soon, but want to do so in a way consistent with the rules, guidelines, and norms of the site/community, assuming of course that such a thing is possible. Editing a question with a completely new proof attempt might work and be preferable in my case, but it would not be a good option if the original question already had an answer.
What are the current rules as they stand now?
If there isn't an explicit rule for this, I propose the following rule for consideration
- You must wait 90 days before posting a new solution attempt.
- The approach taken by the new solution attempt must be substantially different from all previous attempts.
- You must include a link to all previous attempts in your new attempt.
Also, do these sorts of questions benefit the community? I think they have some value when the proof attempt is actually correct, because the asker will not use advanced techniques outside their background.
