   Abstract:
   © 2020 American Mathematical Society. M. Levine proved an enrichment of the classical Riemann–Hurwitz formula to an equality in the Grothendieck–Witt group of quadratic forms. In its strongest form, Levine’s theorem includes a technical hypothesis on ramification relevant in positive characteristic. We describe what happens when the hypotheses are weakened by showing an analogous Riemann–Hurwitz formula and describing an example suggested by S. Saito.
