Is it possible to calculate the derivative of a boolean polynomial in Sage using PolyBoRi?
I can do this for polynomials over GF(2): sage: R.<x,y,x> = PolynomialRing(GF(2),3) sage: f = 3*x^2*y + 2*x*y + y + 9*x^2 + 5*x - 3 sage: f x^2*y + x^2 + x + y + 1 sage: f.derivative(x) 1 sage: f.derivative(y) x^2 + 1 However I cannot do the same for boolean polynomials: sage: B.<x,y,z> = BooleanPolynomialRing(3) sage: f = 3*x^2*y + 2*x*y + y + 9*x^2 + 5*x - 3 sage: f x*y + y + 1 sage: f.derivative(x) AttributeError: 'sage.rings.polynomial.pbori.BooleanPolynomial' object has no attribute '_derivative' sage: Maybe this is not implemented or maybe i am not doing sth. right?
