I just was wondering what is the meaning of this symbol
[itex]\stackrel{\smile}{\frown}
[/itex].
It is used in the terminology of estimation of norms, I do not know if it is a standard notation, since I did not find anymore explanations. Also I do not know if there is a command to write it directly by LaTeX instead of "\stackrel{\smile}{\frown}".
Thanks in advance.
