Multiplicator freeness for restricted-ramification Galois groups over global function fields

Let $K$ be a global function field with full constant field $\mathbb{F}_q$, let $T$ be a finite set of finite places, and let $\infty$ be a distinguished place. We study the maximal pro-$\ell$ extension of $K$ which is unramified outside $T$ and in which $\infty$ splits completely. Using factorisati
