Function

ExtendField ( mdl M, fld^fin L ) -> mdl, map()

Optional Arguments

Resultselt-ord^rat1 <= Results <= 2

Description

Given an RModule M with base ring K, a finite field, and L an extension of K, construct the RModule N with base ring L obtained by lifting the components of elements of M into L, together with the inclusion homomorphism from M into N.

Examples

x_F17:=FiniteField(17);x_M:=KModule(x_F17,2); x_2F17:=FiniteField(17,2);ExtendField(x_M,x_2F17);
