BBF.RetrieveWPrimeLTs

Retrieve leading terms of polynomials of W'.

Syntax

BBF.RetrieveWPrimeLTs():LIST
BBF.RetrieveWPrimeLTs(Degree:INT):LIST

Description

The first function without parameter retrieves the leading terms of the polynomials of W' from the ApCoCoABBFServer. The second function with parameter Degree >= 0 retrieves the leading terms of degree Degree of the polynomials of W'. Please note that in order to use this function you have to start the ApCoCoABBFServer.

  • @param Degree Retrieve the leading terms of degree Degree from the polynomials of set W'.

  • @return List of leading terms of polynomials of set W'.

Example

Use Z/(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.RetrieveWPrimeLTs();

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

Example

Use Z/(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.RetrieveWPrimeLTs(2);

Output:
[ ]
