BBF.RetrieveBorderBasis
Retrieve computed border basis.
Syntax
BBF.RetrieveBorderBasis():LIST
Description
Retrieve the computed border basis from the ApCoCoABBFServer. Please note that in order to use this function you have to start the ApCoCoABBFServer.
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.Finish(); -- After computation has finished: BBF.RetrieveBorderBasis(); Output: [z^2, y^2 + 8001, x^2 - 8001, yz^2, y^2z + 8001z, xz^2, xy^2 + 8001x, x^2z - 8001z, x^2y - 8001y, xyz^2, xy^2z + 8001xz, x^2yz - 8001yz]
