BB.LiftHomAS

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

Syntax

BB.LiftHomAS(OO:LIST):LIST

Description

Compute the equations defining the homogeneous border basis scheme and coming from the lifting of across-the-street neighbours. The input is a list of terms OO (2nd element of type POLY). The output is a list of poly in the ring BBS=K[c_{ij}].

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

  • @return A list of generators of the homogeneous border basis scheme ideal that results from the lifting of across-the-street neighbours in the border of OO. The polynomials will belong to the ring BBS=K[c_{ij}].
