I'm using $\frac{\smile}{\frown}$ as an approximation to a symbol that

stands for a relation between two functions. So I would like

$f\frac{\smile}{\frown}\phi$ to be spaced like $f\approx\phi$, say. How

may I do that?

Should it be of interest to anyone, the symbol I'm approximating is on

page two of G.H. Hardy's /Orders of infinity/. If anyone knows of that

symbol precisely so that I don't have to roll my own, please tell!
