Abstract
Let be a discretely valued Henselian field. Creutz and Viray show that the degree set of a curve over a -adic field can miss infinitely many multiples of the index of , a phenomenon that cannot occur over finitely generated fields. For curves with a cyclic cover of of prime degree, under mild assumptions, we completely characterize how and when this behavior can occur, and give a method for computing degree sets of curves of this type.
