Computes the homogeneous border basis scheme generators obtained from lifting of AS neighbours.

Syntax

BB.LiftHomAS(OO:LIST):LIST

Description

This command computes the equations defining the homogeneous border basis scheme and coming from the lifting of across-the-street neighbours.

  • @param OO A list of terms representing an order ideal. The second element is of type POLY.

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