This article is about a function from ApCoCoA-1.

BBF.RetrieveUGenerators

Retrieves generators of the order ideal.

Syntax

BBF.RetrieveUGenerators():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 set of generators of the order ideal U representing the computing universe from ApCoCoABBFServer.

  • @return List of generators of order ideal U.

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.RetrieveUGenerators();

Output:
[xyz^2, xy^2z, x^2yz]
