Char2.GBasisF2

Computing the unique F_2-rational solution of a given polynomial system over F_2.

Syntax

Char2.XLSolve(F:LIST):LIST

Description

Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use it/them.

This command computes the unique F_2-rational solution of a polynomial system over F_2 = Z/(2).

  • @param F A system of polynomial equations over F_2 having a unique solution.

  • @return The unique solution of the given system in F_2.

Example

Use R::=QQ[x,y,z];
I:=Ideal(x-y^2,x^2+xy,y^3);
GBasis(I);
[x^2 + xy, -y^2 + x, -xy]
-------------------------------
Use Z::=ZZ[x,y,z];
-- WARNING: Coeffs are not in a field

I:=Ideal(x-y^2,x^2+xy,y^3);
Char2.GBasisF2(I);
-- WARNING: Coeffs are not in a field
