BB.GenericBB
Computes a generic border basis.
Syntax
BB.GenericBB(OO:LIST):LIST
Description
Computes the "generic" border basis w.r.t. an order ideal OO i.e. the polynomials g_j = b_j - \sum_i c_{ij} * t_i. The output is a list of POLY in a "universal family ring" UF where UF=K[x_1,..,x_n,c_{ij}].
@param OO A list of terms representing an order ideal. The second element has to be of type POLY.
@return A list of generic border basis polynomials w.r.t. to an order ideal OO.
