No, since the noise to signal ratio is going to be terrible. You have a much better chance on a site whose users are all experts and which gets less traffic. A rule of thumb is that if you're not sure, post here. Worst case scenario, you can always go on meta.MO and ask if that question is suitable, or something like that. A slightly more specific rule of ...

How can I choose the preferred website to put my questions? I once read something along the lines "If you have to ask whether to ask on MO or math.se, likely you should ask it on math.se." I think this is a good rule of thumb. What if someone writes his or her question down on the not preferable website? If you post on MO and they think it is ...

Sometimes you want to have pizza for dinner. And that's fine. You call the local pizza place, and you order pizza which is delivered to your house usually within 30 minutes. What you don't do is neither call several pizza places and see which one gets first to your place; or call a falafel place, and order a large pizza with extra mushrooms. When do you ...

I think you should err on the side of just asking on MathOverflow. There aren't enough interesting questions on MO these days anyway. If you're worried about your reputation (in the colloquial sense) post under a pseudonym.

There are a few things here: In order to migrate a question to MathOverflow one should flag it for moderator attention and request that the question will be migrated. Either the moderator who handled the flag is sufficiently knowledgeable in the field and can do it themselves; or they consult a MathOverflow moderator/user for the suitability of the question ...

My opinion is that questions should only be marked as duplicate only if they are on the same site. For example, if the same question is asked on the site for professional linguists and on the site for English language learners, it requires different answers and different level of detail. Perhaps the difference between MO and MSE is not that big, but there ...

While the idea is in principle reasonable, that's not a recommended use for tags on Stack Exchange. It would be a so-called "meta tag". A tag on Stack Exchange should describe the subject of the question, not the type of the question, and certainly not extrinsic aspects. If you come across such a question your options include: copy the answer from ...

Here's a step-by-step: Wait a sufficient number of days. (At least one week.) This is just in case someone on Math.SE can answer your question. Flag for moderator attention. Request the moderators to move the question to MathOverflow. At this point, one of two things may happen (though it may take a few days). One of the Math.SE mods with some expertise ...

Since June 25, 2013. See: MathOverflow 2.0, History of MathOverflow. Generally, meta.MO is a better place for questions about MathOverflow. The sites (oops, they are no longer sites but communities) are quite different in their focus and thus they complement each other instead of being competitors. Occasionally, people ask: If I have a maths ...

Let's at least implement this for very popular arXiv-style tags (ag.algebraic-geometry and such) — it's useful both for migration and for (admittedly rare) visitors from MO asking questions here. On the other hand, creating synonyms for numerous small tags (like recurrences used for less than 50 questions on MO) seems (to me) to be an overkill.

Thanks to the helpful links posted in the comments by Martin Sleziak, I obtained a precise answer to the question here. The answer, on MO Meta, was to a question about cross-posting in the opposite direction, but it explicitly dealt with both directions. The answer, which was the sole answer to the question and by a high-rep poster, was well upvoted and ...

You cannot ask questions on Mathematics Stack Exchange because you are currently question banned. This ban is automatic and kicks in when some algorithm decides that your question contributions are of poor quality, and are not of positive value to the community. In contrast, you are not question banned on MathOverflow. Though both sites are part of the ...

It depends on what you want the answers to be like. There's a certain difference in tone between MO and MSE posts stemming from the expected audience. MO is full of real deal, bona-fide, research level mathematicians; MSE has some of those, but also undergraduates, math hobbyists, and research types from other fields. Answers on MO assume a certain level of ...

I have answered or commented on some of the questions of the OP, which are very much in my area. I can propose a possible reason why "most questions are unsolved yet, some of them up to a month old". Of course, many people on this site are willing to try to answer technical questions, and at least in logic there are a number of experts active here and also ...

While the topics are different, a blog post that Robert wrote some time ago explores the reasoning behind 'splinter' sites, and under what reasons we'd support them. There are also technical considerations to speak of, MathOverflow was an autonomous SE 1.0 site not connected to the Stack Exchange network in any way for a very long time. They've been part of ...

There is one more factor which should be taken into consideration when deciding whether to use MathOverflow or Mathematics and that is the level of answers you expect. (IIRC this was mentioned several times in the rather heated debate shortly after MO joined SE network: What, when and will we migrate questions to MO 2.0?) According to description given on ...

Done. See https://math.stackexchange.com/help/on-topic I also moved the caveat about Mathematica up a bit: the site is now graduated and people really are much, much better off asking Mathematica questions there than here.

I have keyed in the synonym mappings for most of the arXiv tags. A few slight mismatches: ca.analysis-and-odes points now to analysis; ODE questions will need retagging manually after migration from MO. ra.rings-and-algebras now maps to abstract-algebra. cv.complex-variables goes to complex-analysis. qa.quantum-algebra becomes quantum-groups. kt.k-...

Are my questions too difficult for SE? No. But more importantly, it's not the perceived difficulty of a question that determines whether it's a good fit for MSE or MO. Any math question that's self-contained, isn't too broad, is well-written (and more generally is a well-asked question) is welcome. Sometimes people ask questions that end up not being ...

It is considered as admissible to ask a question on both sites if all of the following conditions are met: A reasonable amount of time has passed between the two postings (a week). References in both directions are provided (it'd also be nice if once you get an answer on one site you "transfer" the knowledge to the other as well). Of course the questions ...

Since there weren't that many links, I've gone through them manually and fixed what the searches turned up here on meta (flooding the front page, but I thought that would be less annoying than spreading the edit operation over weeks doing two a day ;). On main, there are fewer links, those will be dealt with manually too.

About the background: MathOverflow is being done by a non-profit organization which pays for the SE for their site. MathSE is an SE site about mathematics, started by the community with the ordinary Area51 site construction procedure. The MO was started in the era as the rules of the SE weren't so strongly fixed. As far I know, currently this option is not ...

I would recommend cross posting over migration, both because then you don't have to worry about time limits and because you get more exposure that way. I have done this once (I've only ever posted 11 questions on MSE). You can see the original post and then the Overflow cross post. My cross-post was well received, with 18 upvotes and 5 stars, and asked 12 ...

You will not receive a notification when your request is denied. To see whether a decision on your flag was taken already or whether it is still pending you check your flag history (see A way to view your flags) Generally, a request for migration being a flag will be handled by the site's moderators as they see fit and when they have the time to do so. ...

According to the MathOverflow history page here, MO joined the StackExchange network on June 24, 2013. Thus, it is now automatic. (You can click the SE link at the top left of the page and then click MathOverflow and sign up.)

If I understand your question correctly, you are asking whether the OP can migrate question by themselves or whether some intervention by the moderators is needed. The question cannot be migrated by the OP. If you want to migrate your post to MO, you should flag the question for moderators attention and explain in the flag that you want to migrate the ...

I've looked at the Question at issue, and I think it not in good shape for Math.SE or MathOverflow. It asks about "how many" functions of three variables cannot be expressed as a composition of two bivariate functions in a particularly constrained way, namely that $T(x,y,z)$ cannot be expressed as either of these forms:  f(x,g(y,z)) \;\text{ or }\; f(g(x,...

Do not be afraid. Most* MO users will, when they see an off-topic question, vote to close it. If it is closed (put "On Hold" as they say here), then you can ask to have it migrated to M.SE if you wish.

There's not much that we can do except downvoting and closing their stuff with a comment that asks them to replace their text images with the appropriate text. When they've made the demanded changes, the downvote and close vote would be retracted.
