This article is about a function from ApCoCoA-1.

BBF.RetrieveWPrime

Retrieves polynomials from W'.

Syntax

BBF.RetrieveWPrime():LIST

Description

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

This command retrieves all polynomials from W'.

  • @return List of polynomials of set W'.

Example

Use ZZ/(32003)[x, y, z],DegLex;
I:=Ideal(-4*x^2 + 1, -4*y^2 - 1, 5*z^2);
BBF.Init(I);
BBF.Steps(10);
-- After computation has finished:
BBF.RetrieveWPrime();

Output:
[x^3 - 8001x, x^2y - 8001y, x^2z - 8001z, xy^2 + 8001x, y^3 + 8001y, y^2z + 8001z, xz^2, yz^2, z^3]
