BBF.RetrieveVPolysWithTermInSupport

Retrieve polynomials with specific support term from V.

Syntax

BBF.RetrieveVPolysWithTermInSupport(T:POLY):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.

Retrieve all polynomials from V that have the term T in their support.

  • @param T All polynomials in V with this term in their support will be retreived.

  • @return List of polynomials of set V.

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(20);
-- After computation has finished:
BBF.RetrieveVPolysWithTermInSupport(z);

Output:
[x^2z - 8001z, y^2z + 8001z]
