comment Finding inverse of polynomial in a field
@miloszmaki: Remember that the polynomials have coefficients in $\mathbb F_3$, so that $4 = 1$ and $1/2 = 2$ and $-1 = 2$. Thus the solution you propose is actually the same as mine.

comment Alternating sum of multiple zetas equals always 1?
The proof doesn't generalize to non-integer arguments since $z_m = x^{m-1}y$ only makes sense if $m$ is a natural number. But maybe the result for natural $m$ implies the result for non-integer $m$ by the identity theorem. If $m \mapsto 1-A_m$ is holomorphic on a connected open subset $D$ of the Riemann sphere containing $\mathbb N$ and the point at infinity, then since $\mathbb N$ has the point at infinity as limit point, the identity theorem forces $1-A_m$ to vanish on all of $D$.
