In this paper we study division algebras over the function fields of curves over Q p . The first and main tool is to view these fields as function fields over nonsingular S which are projective of relative dimension 1 over the p adic ring Z p . A previous paper showed such division algebras had index bounded by n 2 assuming the exponent was n and n was prime to p. In this paper we consider algebras of prime degree (and hence exponent) q = p and show these algebras are cyclic. We also find a geometric criterion for a Brauer class to have index q.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
