## 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}]`.
