If you have posted a question at MSE and want to cross-post it at MO or the other way around, you can do it under the following conditions: Wait several days, not just hours. I would suggest a week. Provide links between the two versions. The MO question should have link to the one at MSE and vice versa. (This is for honesty and avoiding duplicate efforts ...

Yes, one should be closed as off-topic, and migrated to the other site, where it can be closed as a duplicate. It's a bit painful that we can't close as a duplicate of a question on another site, but that's the present state of things. I think the majority of cross-posted questions will be off-topic for MO and on-topic on MSE, but not all. I see you're not ...

You can flag the post for moderator attention on MSE, choose the free-form flag and ask for a migration to MO. Another option, which is useful when the crickets really chirp, and you haven't got any comments either, is to simply delete the question and post it anew on MO.

I would have nothing against such a question on MO. My guess is that it would be well received here. But I'm not a specialist in the topic, so you should not go by my word only. If you migrate it from CST to MO, you will lose your CST audience. If you feel that the MO community probably cannot answer all aspects of the question, it might make sense to cross-...

The reason to wait a week or so before crossposting is to avoid having someone spend a lot of time trying to answer on one site, without realizing that it's already answered on the other. After a week, it's less likely that anyone is actively working on it. Additionally, you must edit every copy of the question to include a link to every other copy. ...

IMO, yes, that's definitely a graduate-level topic, and so appropriate for MO in that respect. (And I say that as a grad student who's studied delay equations a little.) AFAIK, cross-posting should not be a problem in a case like this, if disclosed properly (i.e. with links both ways). You could also consider simply deleting your question on MSE, since it ...

The suggestion in this post is only about cross-posts, by which I mean that a user posts the same question at the same time on both sites.1 But very probably this is the same thing what the OP meant by cross-post. If the questions is left on both sites and it is, for example, closed on MO and answered on MSE, MO will be left with the closed question. If the ...

I would like to second @quid's comment, especially the latter half: Although there is some overlap between the communities, the scope of scicomp and MO is sufficiently different that it makes sense to tailor your question to each site: Have a common introduction describing the problem and the background, and a second section with the specific question -- ...
