Title
Computing local Artin maps, and solvability of norm equations
Abstract
Let L = K ( α ) be an Abelian extension of degree n of a number field K , given by the minimal polynomial of α over K . We describe an algorithm for computing the local Artin map associated with the extension L / K at a finite or infinite prime v of K . We apply this algorithm to decide if a nonzero a ∈ K is a norm from L , assuming that L / K is cyclic. References References 1 V.
