Let \(k\) be a global function field with constant field \(\mathbb{F}_{q}\). Let \(\infty\) be a place of \(k\) and let \(\mathbb{c}_{k}\) be the ring of functions regular outside of \(\propto\). Once a sign function has been chosen, one can define a discriminant function on the set of rank 1 Drinfe
