Restricted Witt algebra and analog of Fermat's Theorem
I found this interesting result in the work of D. B. Fuchs and T. Evans(2002), and also I have proved this result using Bell polynomials. However, I suppose that there should be more easier solution. Any ideas?
Let $D=ffrac{d}{dx}$ be an operator and $f$ be a function of $x$, so
$D^{p-2}(f)+frac{d^{p-2}}{dx^{p-2}}left(f^{p-1}(x)right)equiv 0;(mod; p)$

I assume the $f$ in $D$ is the same as in $f$?
