My belief is that it is legitimate to cite some posts of the main site MathOverflow in the classroom of some course. Under this assumption I've wondered about the following question.

I don't know those but I'm curious about the typology of different courses that are taken in different departments of mathematics or institutes of mathematics, I know the denomination of these courses but I don't know what is the meaning, motivation, scope or audience of these courses: seminars, courses that are taken by or whose instructor is a postdoctoral researcher, courses by visiting professors, crash courses, summer school of mathematical societies or universities,….

Question.I would like to know if the posts of MathOverflow are potentially interesting (I evoke the study of some theorem, example or open/research problem…) in the context of the teaching of some course for professional mathematicians, see the previous list.Many thanks.

Isn't required specify what specific theorem or example or open problem you've in mind, just I'm asking if in general if it could be interesting cite and to study posts in courses for professional mathematicans: in what situations are you thinking and why (please justify your words).

I hope that this question is interesting and suitable for this Meta, feel free to add your feedback in comments. Yesterday I've edited and deleted the post on the main site MathOverflow, *this post with identifier* **438468** I hope your feedback: I think that the question is interesting.

whythese were good lessons/matheatical lectures, your motivation, the goals that you had in mind... and other details that you consider important in the context of my Question). $\endgroup$
