BBF.RetrieveWPrimeLTs
Retrieves leading terms of polynomials of W'.
Syntax
BBF.RetrieveWPrimeLTs():LIST BBF.RetrieveWPrimeLTs(Degree:INT):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.
The first variant of this command without parameter retrieves the leading terms of the polynomials of W' from the ApCoCoABBFServer. The second variant with parameter Degree >= 0 retrieves the leading terms of degree Degree of the polynomials of W'.
@return List of leading terms of polynomials of set W'.
The following parameter is optional.
@param Degree Retrieves the leading terms of degree Degree from the 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.RetrieveWPrimeLTs(); Output: [x^3, x^2y, x^2z, xy^2, y^3, y^2z, xz^2, yz^2, z^3]
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.RetrieveWPrimeLTs(2); Output: [ ]
