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?
$2^{\overset{\omega}{\smile}}$ought to work. – egreg Sep 03 '15 at 07:58\text{}you can use\ensuremath{\omega}, but as egreg showed, do that in this example is obviously meaningless. – Fran Sep 03 '15 at 08:34
