ApCoCoA-1:BB.BBasis
From ApCoCoAWiki
BBasis
border basis of a zero-dimensional ideal
Syntax
BBasis(I:IDEAL):LIST of POLY
Description
Let <formula>\sigma</formula> be a degree compatible term ordering. The function BBasis calls the ApCoCoAServer to compute the <formula>\mathcal{O}_\sigma(I)</formula>-border basis of the zero-dimensional input ideal I and returns it as a list of polynomials.
Example
Use Q[x, y], DegLex; I := Ideal([x^2, xy + y^2]); BB := BBasis(I); BB; ------------------------------- [xy + y^2, x^2, y^3, xy^2] -------------------------------
