I asked a math question https://math.stackexchange.com/q/4475036/342834 in an area where physicists are likely to have a great deal of practical background. I had originally intended to post the Physics SE, but forgot to switch communities. I believe posting the same question to both communities is frowned upon. If I wanted to move this question to the physics community, how should I do it?
Click the flag link under your question and choose the option In need of moderator attention, then leave a message for the mods asking to migrate the question.
However it isn't clear to me whether the question would be better here. Maybe give it a few days where it is and request a migration if you don't get and answer on the Math SE.
