I asked this question in Math Stack Exchange several days ago, but I have received no interaction so far, apart from 4 upvotes. I was considering adding a bounty, but since (to my humble understanding) the question seems to be of research level, I was wondering if it would be appropriate to post it here instead after a week or two, in the case that I get no feedback in MSE during that time.
Of course I would reword the question to make it more concise, and perhaps modify its scope to avoid duplication of content.
Around eight months ago I did a similar thing with another question (MSE version, MO version). The question turned out to be well-received here and had a helpful answer. But I think this case is different, because it is about a generalization that I haven't seen even mentioned in the literature I've checked, and since I'm not a professional mathematician (my background is in physics) I don't have the knowledge to discern whether it's because it has a trivial answer, because it is too broad to answer or even if the question is ill-posed.
Is my question suitable for MathOverflow in its current state? If not, are there any modification(s) I could make so that it becomes suitable?
EDIT: Thank you all for your help! The question is now posted here.
