Genus fields of finite abelian extensions

Number Theory 2017-10-24 v2

Abstract

In this paper we find the genus field of finite abelian extensions of the global rational function field. We introduce the term conductor of constants for these extensions and determine it in terms of other invariants. We study the particular case of finite abelian pp--extensions and give an explicit description of their genus field.
