BB.HomASgens

Computes the generators of the vanishing ideal of a homogeneous border basis scheme.

Syntax

BB.HomASgens(K:INT,OO:LIST):LIST

Description

This command computes the generators of the vanishing ideal of the homogeneous border basis scheme corresponding to the lifting of the K-th element of BB.ASneighbors(OO).

  • @param K An integer K in the range 1..Len(BB.ASneighbors(OO)).

  • @param OO A list of terms representing an order ideal.

  • @return A list of generators of the vanishing ideal. The polynomials will belong to the ring BBS=K[c_{ij}].
