A ruled residue theorem for function fields of elliptic curves

Commutative Algebra 2023-12-13 v2 Number Theory

Abstract

It is shown that a valuation of residue characteristic different from 22 and 33 on a field EE has at most one extension to the function field of an elliptic curve over EE, for which the residue field extension is transcendental but not ruled. The cases where such an extension is present are characterised.
