Explicit genus formula for any separable cubic global function field

Number Theory 2018-11-27 v1

Abstract

In the present work, we determine explicitly the genus of any separable cubic extension of any global function field given the minimal polynomial of the extension. We give algorithms computing the ramification data and the genus of any separable cubic extension of any global rational function field.
