AF+BG theorem the greatest common divisor of "f" and "g". The AF+BG condition expresses, in terms of divisors (sets of points, with multiplicities), a similar condition under which a homogeneous polynomial "H" in three variables can be written as an element of the ideal generated by two other polynomials "F" and "G". This theorem is also a refinement, for this particular case, of Hilbert's Nullstellensatz, which provides a condition expressing that some power of a polynomial "h" (in any number of variables) belongs to the ideal generated by a finite set of polynomials.
