uppose that $\mathcal{R}^{{\ifm {{\sf wt}} {{$\sf wt$}}}}$ is a zero divisor in ${\overline{{\mathbb F}}_{\hskip-0.0mm q}}(A_s {\ifm {,\ldots,} {$,\ldots,$}}A_0)[A_0,A_0]/(\mathcal{S}_0^{{\ifm {{\sf wt}} {{$\sf wt$}}}_0})$. Since $\mathcal{S}_0^{{\ifm {{\sf wt}} {{$\sf wt$}}}_0}$ is irreducible, we have that $\mathcal{R}^{{\ifm {{\sf wt}} {{$\sf wt$}}}_0} \in (\mathcal{S}_0^{{\ifm {{\sf wt}} {{$\sf wt$}}}_0})$, which can be s
