SolomonTeraoIdeal

Solomon-Terao ideal of an arrangement of hyperplanes wrt a poly

Syntax
SolomonTeraoIdeal(A: LIST, f: RINGELEM): IDEAL

Description
This function returns the Solomon-Terao ideal of the list A of hyperplanes of an arrangement respect to a polynomial f.

Example
/**/ use QQ[x,y];	
/**/ A := [x, y, x-y];
/**/ f := x^2+y^2;
/**/ SolomonTeraoIdeal(A, f);
ideal(2*x^2 +2*y^2,  2*x*y^2 -2*y^3)
