Yesterday I posted this questionthis question on Mathematics Stack Exchange. Except for the one upvote it didn't receive any attention. What is the problem with my question? Is it too vague? Should I better include an example? I am hesitating whether I should have posted the question on MathOverflow instead of this SE. Should I change the location of the question?
