Dec 20, 2017 at 0:26 | comment | added | LSpice | What is $h$ in your second paragraph? It looks like you're defining $g$, but the rest of your exposition suggests you still want $g : n \mapsto n f(n)$. Are you defining $h$ by the equation $g(n) = h(\phi(n))$? If so, then is the idea that $h$ is defined arbitrarily on numbers that aren't $1$ modulo $x$? (In the same vein, what does $g((n - 1)/x)$ mean when $n \not\equiv 1 \pmod x$?) | |
