# \smile underneath the exponent [duplicate]

I'd like to write a formula where there is a $\smile$ underneath the exponent.

Like in this example which works fine:

 $2^{\overset{\text{blabla}}{\smile}}$


But when I want to replace the blabla by a mathematical symbol like $\omega$ it does not work.

Any suggestions?

• I have no problem. A minimal (non-)working example, maybe? – Bernard Sep 3 '15 at 7:50
• $2^{\overset{\omega}{\smile}}$ ought to work. – egreg Sep 3 '15 at 7:58
• Inside \text{} you can use \ensuremath{\omega}, but as egreg showed, do that in this example is obviously meaningless. – Fran Sep 3 '15 at 8:34
