This article is about a function from ApCoCoA-1.

BBF.RetrieveBorderBasis

Retrieves a computed border basis.

Syntax

BBF.RetrieveBorderBasis():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 the computed border basis from the ApCoCoABBFServer.

  • @return List of border basis polynomials.

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.Finish();
-- After computation has finished:
BBF.RetrieveBorderBasis();

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