Abstract

We survey our recently proposed method for constructing biholomorphic invariants of quasihomogeneous isolated hypersurface singularities and, more generally, invariants of graded Artinian Gorenstein algebras. The method utilizes certain polynomials associated to such algebras, called nil-polynomials, and we compare them with two other classes of polynomials that have also been used to produce invariants.

Notes

  1. 1.

    The proof of this proposition given in [6] was suggested to us by A. Gorinov.

  2. 2.

    This formula for the discriminant of a ternary cubic differs from the general formula given in [12] by a scalar factor.
