Real Seifert form determines the spectrum for semiquasihomogeneous hypersurface singularities in C3
We show that the real Seifert form determines the weights for nondegenerate quasihomogeneous polynomials in C3. Consequently the real Seifert form determines the spectrum for semiquasihomogeneous hypersurface singularities in C3. As a corollary, we obtain the topological invariance of weights for nondegenerate quasihomogeneous polynomials in C3, which has already been …
