# How to add ~ on top of a greek letter [duplicate]

How can I add ~ on top of a greek letter?

I have tried $\~\upsilon$ for example. For hat, I used \hat{\upsilon} in math mode.

• $\tilde\upsilon$? It is really hard to tell something specific with that little information. – Johannes_B Dec 4 '16 at 8:37
• Do you need this in regular text or mathmode only? Do you need more greek letters with accents? – Johannes_B Dec 4 '16 at 8:38
• May this link be useful? – CarLaTeX Dec 4 '16 at 8:41
• I need it in math mode only. I suppose $\tilde\upsilon$ was what I wanted. Thanks. – ARK Dec 4 '16 at 8:58

As @Johannes_B suggested in the comment, it seems \tilde\upsilon does what I need to do in math mode.
