Function

NormGroup ( fld^abl F ) -> map(), elt-ids^int/ord^num, seq()

Optional Arguments

Resultselt-ord^rat1 <= Results <= 3

Description

The norm group of F, i.e. a map from an abelian group into the ideals, the defiing ideal and the infinite places.

Examples

x_o := MaximalOrder(X^5-5*X^3+7*X^2-15*X+16); x_cl := ClassGroup(x_o); x_ab := AbelianExtension(x_cl.ext1); NormGroup(x_ab);
