# posting an unanswered Math.SE question on MathOverflow

I have a question on Math.SE which hasn't received any responses. Is it alright to repost it to MathOverflow? If so, how long should I wait before doing so?

• It all depends on what the question is. Why don't you link to it? – Todd Trimble Mar 19 '14 at 16:53

• Does $\Gamma_I(M)$ mean $H_I^0(M)$? If not, the notation should probably be explained. – Todd Trimble Mar 19 '14 at 21:37
• @ToddTrimble yes, it does. – Avi Steiner Mar 20 '14 at 1:02
• If you post it here, be sure to indicate both here and there that the question has been posted in both sites (add links); if you get an answer in one, you should also indicate this fact in the other site (to prevent duplication of efforts). – Arturo Magidin Mar 21 '14 at 3:46
