Package borderbasis

From ApCoCoAWiki
This article is about a function from ApCoCoA-2. If you are looking for the ApCoCoA-1 version of it, see Category:ApCoCoA-1:Package borderbasis.

This page describes the borderbasis package. The package contains various functions for computing with border bases of order ideals in a polynomial ring P=K[x_1,...,x_n] over a field K. We refer the book [M. Kreuzer and L. Robbiano, Computational Commutative Algebra 2, Springer-Verlag, Berlin, 2005] for more details about border bases. For a complete list of functions, see also Category:Package borderbasis.

The Global Alias of the package is BB.

IsOrderIdeal

IsOrderIdeal(OO): checks whether OO is an order ideal.
     input: OO a non-empty set of terms in K[x[1..N]]
     output: boolean value for checking OO being an order ideal
