This article is about a function from ApCoCoA-1.

BBF.RetrieveBorderBasisPolyByLT

Retrieves a computed border basis polynomial.

Syntax

BBF.RetrieveBorderBasisPolyByLT(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.

Retrieves the computed border basis polynomial with leading term T from the ApCoCoABBFServer.

  • @param T Leading term of the border basis polynomial to retrieve.

  • @return A border basis polynomial.

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.RetrieveBorderBasisPolyByLT(xy^2);

Output:
[xy^2 + 8001x]
